I had a good run with this app initially, but after one issue it quickly snowballed. Last week I raised concerns about billing inconsistencies that did not match their own pricing table. The initial customer support was extremely disappointing - I received one-line replies to a detailed report and was simply sent a link to the same pricing table I was questioning. For a high-volume store paying around $90 per month, I expected more serious engagement. After pushing back I was escalated to the founder, Ty, who was excellent. He handled the situation professionally and refunded the months in question. To prevent future billing issues he suggested migrating me to their new V2 beta. Unfortunately that decision has been a DISASTER. The V2 beta is highly unstable and introduced multiple serious problems. Upsell data was migrated incorrectly, with deals that required $110 spend reset to a $40 default threshold, something very easy to miss unless you manually check every upsell. This meant customers could unlock significant discounts far below intended spend levels. The cart itself became buggy and unstable, crashing, failing to load images and freezing pages. I was unable to roll back to V1 once migrated, and even disabling upsells and turning the cart off did not fully remove it. A broken version of the cart continued overriding the default Shopify cart. My only option was to uninstall the app entirely to remove the malfunctioning cart from my store. This is particularly frustrating because the app had previously performed well and helped increase AOV, but migrating a live high-volume store to a beta version on a Friday, leaving no weekend support, resulted in significant revenue loss. I am disappointed to leave a one-star review as I respect Ty as a founder and have enjoyed using this app, but based on this experience I cannot recommend it.

Ty, the owner, is exceptional and amazing. He is very reliable and will help you with any questions or solutions you need. You will not regret MonsterCart. They are the best, and they also have an excellent support team.

Unfortunately I have had a terrible experience with this APP. I contacted multiple times during the few months I had this about the dashboard never working the entire time, so I could never check any data. I also have just seen I've been charged multiple times for the same period even though its meant to be a monthly fee on the plan I was on and then also after I finally cancelled I have still been charged again yesterday for another month. I can't contact support now that I have uninstalled and shopify said I need to take the charges up with the app.
Hey team .. Just sent an email. We are in the process of migrating stores to V2 of Monster Cart for analytics. Love to get you sorted there as per conversation. I've also written to you about the charges. Unfortunately this is how Shopify charges our usage and prorata. Its tricky to unpack (please see email) Ty Co-founder Monster Cart

I'm really not so tech savvy, but that's not a problem! The Team at Monster Cart, especially my new best buddy Charlene, was there to help me create a cart that was tailored for my e-commerce site to increase my Average Order Value. It was everything I was looking and hoping for in a tool to help me with my business. Thank you Monster Cart!

Really great app, and the customer service has been phenomenal - reached out to customer service with an issue and had everything fixed within 10 minutes.

Decent app, but picked up that they are duplicating their charges every month. They charge a monthly fee + usage & a monthly fee again. I reached out to their support 2 weeks ago and keep getting a general response that they've passed on the message to the team leader, but still no response. Can you please refund and fix your charges ASAP? Check your charges on your monthly bill!
Hey team 🥰 This is how Shopify system charges with a base charge plus usage separate. This is in-line with our normal pricing listed in FAQs. Really sorry you received a general response message. This should have been communicated day one. Please read the emails I've sent over past weeks. Id love to have the opportunity to make this into a 5 star response. Ty Chapman - Monster Cart Founder

unfortunately support is ghosting me and is not answering to any of my tickets. App stopped working and 20% of orders are not discounted.
Ty here one of the founders. Please respond to the emails we have been sending. I can see the team has been trying to help but aren’t getting responses.

MonsterCart is a really great app! We've tried a fair few similar apps, but have always come back to MonsterCart as the interface is easy yet powerful to use! The customer service is above & beyond, super helpful.

Warning this does NOT work with product variants. It also does not work with subscription products (i.e., excluding subs from upsells) Their product says "fully compatible with product variants" but that does not mean it's possible to do a product upsell with a specific variant. Instead it means that it can apply in the same way to all variants of a product.

I couldn’t be more impressed with the support I received from Charlene at Monster Upsell. From the moment I reached out, she was exceptionally helpful, patient, and knowledgeable. She took the time to fully understand the issue, explained solutions clearly, and went above and beyond to make sure everything was working perfectly. Her communication was fast, friendly, and professional throughout the entire process. It’s rare to find customer support that truly cares, and Charlene absolutely delivered that. Thanks to her outstanding assistance, the entire experience was stress-free, and our store is now running better than ever. Charlene is an incredible asset to the Monster Upsell team, and I’m extremely grateful for her help! Highly recommended support — 10/10!
