Was looking forward to using this app to apply automatic discounts and have the discounts displayed on the product and collection pages but you need to do a ton of coding in order for that to happen and they offer this service for free but it takes 5 days or more and they dont teach you how to do it yourself. Nobody has 5 days to wait, other then that the app is decent.
Thank you for sharing your feedback. I’d like to clarify two points: Our free setup service typically takes less than 24 hours to complete. We mention “up to 3 weekdays” in our documentation to set realistic expectations during peak times or for more complex themes, but in practice, most setups are completed much faster. For merchants who prefer to handle the setup themselves, the app includes direct links to step-by-step instructions on our support portal. We’re glad to hear you found the app itself to be decent, and we’ll continue working to make the onboarding process as smooth and transparent as possible.

We really wanted to use to use this app. It is unfortunately very difficult to use with very limited support. This impacts most of your core shopify files so if you decide to do this you really can't just go back.
Thank you for your feedback, and we're sorry to hear that you're having difficulty using the app. We want to assure you that we provide 24/7 support, and our team is always available to assist with any questions or issues you might encounter. Additionally, Discount Ninja has no impact on your core Shopify files, and uninstalling the app is as simple as a one-click process. We're here to help make your experience as smooth as possible, so please feel free to reach out to us anytime for assistance or guidance!

Customer service is the worst. They send me text with childish content that doesn't seem like a businessman. There is a high possibility that some problems will occur when installing the app. Therefore, customer service is very important. This app is not recommended. If you encounter any problems and some errors occur, there is a high possibility that you will regret implementing the app.
We're sincerely sorry for the difficulties you encountered, especially with the integration with the Transcy app to help you with Japanese text and currency. Your feedback is crucial, and we're dedicated to resolving compatibility issues. As suggested before, we're happy to extend your trial and collaborate on solutions. Your satisfaction means everything to us. Thank you for your understanding.

Never using DN again! Had a promotion set up with their dynamic pricing feature (which we paid more for) for a 2 hour flash sale on our website (50% off). 10 minutes into the promotion running with thousands of customers on our website the app malfunctioned, hundreds of our customers were charged full price and we lost thousands in sales. The issue was unable to be resolved as the sale was only running for the 2 hour period.
Hi there, sorry to hear you had issues with a flash sale in June. To resolve issues with flash sales, Shopify has developed a new way to integrate with the checkout. Discount Ninja is now using this new technique to offer flash sales without limitations!

The app looks super interesting and has a lot of features. We installed it hoping it would help with our conversion rate but it has only caused us trouble. After asking for the support to install the Dynamic Pricing on our theme, we had a bug in our store where after adding a product to the cart, the load button keeps spinning, and also the cart is not being displayed correctly, no product is being shown. They installed the code for Dynamic Pricing and immediately reported this bug and said that it was coming from another app that was installed in our store but we had never used, and never caused trouble. The bug was not happening before the changes did by Discount Ninja, so I asked them to undo the code they had done, they said that I could just install a backup version of the theme and the changes would be undone. I did this and uninstalled both "Discount Ninja" and the other app, but the bug persists. We also talked to the support of the other app (the one they said was causing the bug) and they said: "We have checked this over carefully and can confirm this isn't related to our app. Our app won't edit theme code (specifically to avoid problems like this) - everything is contained in a javascript tag, and when you remove the app you remove the tag. I've checked your site and the tag is no longer there. I hate to point to another developer - but if Discount Ninja have been editing your theme, then it's highly likely the issue is related to them - and I'm pretty certain they will edit your cart too." The theme support is obviously not able to help us because the theme has been changed already. Now I'll have to pay for a developer to solve this issue. Very disappointed. Don't recommend it.
Hi there, we'd appreciate it if you could remove this review immediately as it is both misleading and incorrect. The issue you experienced (loading icon on add to cart button) was caused by a bug in your theme (Maker from Troopthemes, version 4.2.0 released in 2018 - https://support.troopthemes.com/release_notes/maker/#version-4). Claiming that there is a link with Discount Ninja is factually incorrect and affects the perception of our brand and the quality of the app. The Discount Ninja support team spent a great deal of time attempting to troubleshoot this issue for you, but was unfortunately unable to find the root cause as the issue was buried deep in the minified JavaScript file of your theme. I spent some time on it myself and was able to identify the issue. I found the exact line in the theme.min.js where the theme's code fails (due to a call to a non-existent JavaScript function). I sent you a recording that shows precisely where it fails: https://www.loom.com/share/825ef87397a14f6791b95bc3ec0d6038 We're happy to hear that you feel the app is "super interesting and has lots of features". If you choose to reinstall once the problem in your theme is fixed, I'm sure you'll find it can bring great value to your shop. Wishing you all the best!

When it works, it's fine. The problem is that when it breaks, it BREAKS. Support is polite but completely useless. My discounting system has been down for over a week due to a bad update on their part and after THREE "oh, it's fixed now!" messages from support, it's STILL broken. My company has taken a hard hit to reputation for "fraudulent advertising" and we're having to refund hundreds of dollars manually because Limoni Apps support doesn't appear to be able to maintain their own app. Most disappointing app support I've seen to date.
We're deeply sorry for the significant disruption caused by the recent issues with our app. Your experience falls far below our standards, and we understand the frustration and damage it has caused to your business and reputation. Please allow us the opportunity to rectify the situation and provide the support you need. Your satisfaction is our top priority. Thank you for bringing this to our attention.

Something to keep in mind, the free offer isn't 14 days - it's 7 days. I'm still going to try it, but I was hoping for the full 2 weeks to get the feel for it.
The app did indeed briefly state an incorrect number of trial days in the settings screen on the day you installed the app. This mistake has been corrected. Discount Ninja currently offers a 14-day free trial. You're welcome to explore all the features of the app for two full weeks, free of charge.

We used discountninja on all our 4 shopify stores as it can help to create a satisfying automatic coupon. Whilst I found this brings us a lot of trouble 1. customers cannot receive order confirmation email as discountninja created draft orders a lot 2. Discountninja unreasonablely gave out super big discount to our customers, which result in that our customers can get products at 0 dollar or super low price. That caused us a big loss. And when we contacted discountninja, they just told us it's shopify problem without solving it for merchant. So in order to maintain our store in good condition, we have to uninstall Discountninja. Everyone, mind before you install it.
Hi there Govee, we're sad to learn that you have decided to uninstall the app. We hope you will re-evaluate using the app once Shopify fixes the bug that impacted your order confirmation notifications. With regards to the first issue ("1. customers cannot receive order confirmation email"): this **only** impacts customers who choose to use our "stack a discount code in the checkout" feature. This feature is off by default and the limitations related to this feature are clearly marked in the app. When using this feature (off by default), it is a known limitation that some customers, due to a Shopify bug, find that some order confirmation notification emails (based on the standard Shopify template) are not sent out after an order is completed. Discount Ninja (by default) uses the official Shopify Draft Order API to prepare a checkout. This issue has been brought to Shopify's attention in May of 2021 and the Discount Ninja team has worked with Shopify throughout the last six months to help investigate this issue. As of November 2021 Shopify has not yet resolved this issue. We understand that this problem, for the customers that are impacted, can be problematic. We advise customers that run into this to use an alternative solution to send out the order confirmation email for the time being, such as, for example, Klaviyo. An alternative solution is to switch to our discount code based checkout, which is not impacted by this Shopify bug, as we have discussed in our call with Govee on this topic. With regards to the second issue ("2. Discountninja gave out super big discount"): as discussed in our call, when using the discount code mode, the app combines all offers redeemed by the customer into a single discount code. The app allows you to configure which offers can combine to protect against providing a larger discount than expected. Our customer service team can assist in setting this up properly to avoid any issues.

Working with Discount Ninja has been very painful. I really like the idea of everything they offered, but it is just that- an idea. Basically everything they advertised is everything we needed and wanted, so we were willing to pay for their premium plan. You would think that having this plan you would receive a top tier support but Bart did not respond to multiple requests for over 72 hours. Now, the finally reason that we decided to end our partnership was because they were not compatible with subscriptions services which we had installed on our site for some time. That is no fault of their own and I understand if they are not compatible, there's nothing that can be done. This review is more about their customer support. We had issues with their free gifts charging customers the actual amount of their product, which is a huge no-no when you are dealing with customers money. We literally had to refund over 20+ customers which makes our business look terrible. Now, I understand if the reason this was happening was due to the subscription service, but even after letting him know how huge of a priority this was I had to follow up with him over 4 times just to get a response that he was still working on it. Before knowing the root cause he had said it was fixed about 3 times and every time we found out that there was still another issue or was not actually fixed. This app may work for you if you do not have any incompatibilities and do not need any support but it has been a huge nightmare for us. Also, they had so much code inside our live theme. The application that we found now has been so much easier to deal with and is compatible with subscriptions, so there are better choices out there. I would really recommend improving your service to customers if #1: you want to keep customers and #2 you want to avoid bad reviews. If the service was good and the application did not work for us, I would never have taken my time to write this review.
Hi there, Thank you for your review. Sorry to hear that the free gift promotion did not work well with the other apps you have and the specific theme you use. We continue to invest in improving the app to ensure it is compatible with as many themes and apps as possible. Mid-June we released an update (https://releasenotes.discountninja.io/) that allows for better integration with subscription solutions. The free gift capabilities have also been improved. Quick note: the app is a little bit more than "just an idea" ;-) Discount Ninja was created in 2016 and has seen 4 major releases, many more minor releases, and continuous development and UX improvements. It is the most complete promotions app available for Shopify. It combines free gifts, with BOGO, volume discount, Spend x, get y promotions. It also supports stacked discounts, a custom promotion code field as well as Dynamic Pricing to show discounted prices. On top of that, it offers fully configurable building blocks (widgets) to advertise your offers on your store. The app provides the necessary promotions that help Shopify merchants to increase Average Order Value and conversion rates. Our many Shopify and Shopify Plus customers see significant results once the app is integrated properly.

We installed this app because we were looking for some advanced discount options, It was the worse decision we ever made. The installation support of this app is terrible. The app didn't work for our store, but instead of helping us out immediately, they told us to wait for a couple of days or hire a developer. In the mean time we were not able to offer any discounts. In the end, the app worked, but it was making our checkout terribly slow. It took around 5 second to load the cart template, and around 20 seconds to redirect to the checkout. When I told the support about this, they told me that they couldn't do anything about it now because there developers are busy (we even offered to pay!). After that, we wanted to uninstall the app. Although they helped us with removing leftover code quite quickly, they forgot some of the leftover code, so we still had to remove the app by ourselves... Honestly I wouldn't recommend this app to any store owner. It is hard to understand that the support of this app is so terrible for a monthly payment of $70.
Thank you for your review. As discussed on the phone and over email, we are sorry to hear the second and third-level support teams did not have sufficient availability to assist you immediately during your onboarding process. The availability of our technical staff was extremely limited at the moment you installed due to the fact that we were rolling out an important update to the app, which, among other things included improvements in the checkout performance. We apologize for the inconvenience this has caused you. Should you decide to reinstall the app, we will provide you with an extra onboarding call to ensure you can test all the features during your trial!

I requested a refund as their app did not work once with my theme. I have paid them 3 times in a row and their app did not work. Their support was terrible and took to long to work on my store properly. I can't pay for a app if it does not work and can't just pay for support.
Hi there! We have reviewed the charges for the app applied to your account by Shopify. You received one charge only. You installed on November 28, 2020 and uninstalled on January 19, 2021 and benefited from a 14-day free trial. As discussed via email, your claim (paid 3 times in a row) is indeed incorrect. We have also reviewed your support requests. Our support team have helped you with three separate tickets. We're sorry to hear that you feel the support received was insufficient. We'll use your feedback to improve the support we provide for Discount Ninja!

Please don't use this app. I could go down a laundry list about why this is the world's worst app. Seriously stay away
Hi there, Sorry to hear you had a bad experience using the app. I'd be very interested to hear more about your experience to understand what issues you may have encountered. Best regards, Bart

Customer service is slow and no solution is given still. I didn't need the Bronze Plan anymore so downgraded to Free plan so next month I won't be charged. I still had one whole month of the paid plan left but lost all the features. Support told me they don't have automatic downgrade like other subscription services had. I tried to go back to previous plan since I paid for a month the day before but it wanted to charge me again. I've contacted support for help and they said they'll contact the team and would get back to me with any update. It's been almost 3 weeks with no updates. I emailed multiple times throughout the weeks and got the same response.
Hi Jaimie, As discussed over email, we apologize for the delay in getting back to you. Discount Ninja uses the standard Shopify subscription charging system (like most apps). The downgrade/upgrade behavior is implemented by Shopify and can lead to some surprises indeed. I hope the compensation we offered via email meets your approval and that you are enjoying the app!

Slow response of team through email. All the promotions and offers I created from the start were all removed yesterday without Discount Ninja team informing me. The reports on offer usage are all inaccurate. The tagging of discounted items and adding new items are inconsistent, so manual checking of orders becomes a must. There's also the added work of communicating with the customers regarding the errors. The discounts are also not working properly.

Why is it that, after I uninstall your app, it leaves behind all its code in my theme? And when I try to remove it I get errors all of my shop? Now I have all this unneeded bloatware in my theme and no way to remove it? limoniapps-discountninja-additionalproduct.liquid limoniapps-discountninja-badge.liquid limoniapps-discountninja-body.liquid limoniapps-discountninja-cartdiscountfield.liquid limoniapps-discountninja-context.liquid limoniapps-discountninja-context-settings.liquid limoniapps-discountninja-giftbox.liquid limoniapps-discountninja-header.liquid-old limoniapps-discountninja-notification.liquid limoniapps-discountninja-popup.liquid limoniapps-discountninja-promotionsummary.liquid limoniapps-discountninja-stickybar.liquid limoniapps-discountninja-triggerbutton.liquid-old limoniapps-discountninja-volumediscounts.liquid limoniapps-fontawesome-webfont.ttf limoniapps-fontawesome-webfont.woff limoniapps-fontawesome-webfont.woff2
Hi there, Thanks for your feedback! As mentioned over the phone (voicemail) and email the easiest way to uninstall the assets is to use the "Cancel plan" button in the app (available from Settings > Subscription) as described here: https://support.discountninja.io/en/articles/2698217-how-to-cancel-your-subscription This functionality was added precisely to avoid leaving assets behind after uninstalling. The reason Shopify apps leave assets behind after deleting the app is because Shopify removes all permissions of an app when it is uninstalled. Including the permissions an app needs to "clean up". Shopify is addressing this in an update of its product that may land in 2021. Once that is in place the experience for the merchant will be easier. In the meantime, please use our "Cancel plan" button to uninstall. As mentioned in the emails I sent you in this regard we are happy to help you remove those assets (even though they are no longer loaded and as such do not affect the performance of your theme or shop we agree that it is best practice to remove unused files to avoid confusion). We're waiting for your approval to remove those files from your theme. Please reply to our email when you have the time to let us know we can proceed.

Opted for them to instal the code, but they ruined my theme! My checkout button became disabled, so I lost sales all day. I reached out to customer serivce, but no one ever got back to me. In fact, I'm not sure if they ever finished installing the code because they never communicated with me. After two days, I gave up.
Hi there, as discussed in the many emails we exchanged the issue was caused by another app you had installed. As shown in the video we shared the issue is unrelated to our app. Having said that, we acknowledge our support team failed to notify you after setting up Dynamic Pricing on your theme. We have since improved our procedures to avoid this from happening. We’re sorry your experience with the app has not been the best one and we’ll use your feedback to continue improving how we provide the best support possible to our customers.

I installed the app and then tried to install companion app so that, along with the automatic discount, I could offer a discount at checkout. The app hides the discount field at checkout and a companion app needs to be installed in order to correct that. I attempted to download and install the companion app three or four times. Each time I was redirected to a url that didn't exist. I emailed support and heard back only once. Their email instructed me to use a different email address. I sent three email addresses to that address (the original and two follow-up) and never heard back from them. As a result of this, I lost sales. I had advertised a discount with free shipping and wasn't able to offer the free shipping due to not being able to install the companion app. I am very disappointed with this app and it's developers. Their tech support is terrible, at best. I recommend using another app instead of this one.
Thanks for your review. Since February of 2023 the app uses native Shopify functions to apply discounts for a smooth and seamless experience. You'll be pleased to know the companion app has been deprecated!

I would love to be able to use this app seeing as Shopify somehow still doesn't allow stacked discounts, but in the few days I was running it on my site, there were multiple issues and no response from Support. Products that weren't included in my offers were getting discounted and customers were able to use discounts more than once, even though this is not what the settings on my offer specified. I've been waiting over a week for any update from their support team and am just being told "they're dealing with an unusual amount of requests." I've followed up every single day and have been getting the same general response. Out of the 10 days of the free trial, I was able to run the app for 3 days and then had to pause all of our offers due to these issues not being resolved.
Hi there team Munk Pack, Very sorry to hear that your experience has not been good. We are indeed supporting many, many new customers due to COVID-19. We're doing our best to support every customer. I'm happy to review your case personally. You can reach me at [email protected] and I'll set up a conference call for us to discuss this. Apologies again for the capacity issues we are currently experiencing in the support team and hope to speak to you soon. Best regards, Bart Coppens Founder Discount Ninja

I tried this app and it didn't work. They reached out and supposedly fixed it, however today I've had 2 sales where people got their entire order for free due to some screw up with this app. Uninstalling, I'm done. Don't bother contacting me.
Feb. 12, 2020
If you want to do BOGO/BXGY or free gifts. It does not support variants so basically if you want to give a $10 gift cards as a gift the customer could technically select the highest value.
Thank you for your review. I confirm we do not offer discounts for specific product variants. You can always let our five-star support team know about feature requests you may have. In the meantime you're welcome to try the many other features our app offers today!
