Monster CartUpsell — Free Gift

Wow! The customer service is impeccable! I’m a newbie and the app is so easy and user friendly. I was stuck on one bit and spoke to Charlene who fixed it immediately. We are so happy with supporting them.

Amazing customer service from Angelica, and the team. On a Sunday too! Thanks team :)

Awesome support team that area always quick and happy to help!

In addition to increasing my AOV, Monster Cart goes above and beyond. At one point I thought I was having an issue with My cart and asked the team at Monster Cart to fix the issue. Not only did they figure out the issue was not with their cart but they also figured out what the issue was and how to fix it. The issue was with a totally different app but they put in the extra effort to ensure my shop was up and running correctly. Well done Monster Cart Team! V/R Reese It’s All Good Seasoning

Support has always been helpful when needing to make custom changes to the cart drawer. Great experience!

Love this app sooooo much. SUPER easy to use, and what I like most is if you need help, they are super helpful over email. 1000/10 will continue using this!! Thank you guys!

So far customer service is excellent. A representative immediately found an error in a change I was making. She alerted me to it and has developers ready to fix it. This was probably the fastest I have ever had someone help me on any part of my business. Thank you Angelica!

easy and fun to add to your shop!

Charlene was 10/10 support she helped me so much as well as educated me on the features of the app!!!!

Great customer service and customizations on various cart types. I've been really happy with the adaptability of the carts/offers and have been able to easily tie the aesthetic in to match my store and product. Encountered some issues integrating with other high-level apps in store, but with the devs help we have been able to navigate through that as well. Thanks Monster Cart team :)

We've used Monster Cart Upsell for several years now and it works well. Their customer support is also very quick to respond. Their live chat isn't always available, but if you start a chat they will email you back pretty quick. I've also given them access to my online store several times and they're able to fix issues for me. 5/5 stars!

Solid app, great customer support. I found and reported a bug which the team promptly fixed within 48 hours.

The guys are MonsterCart are super helpful from the get go.

Super easy to set up and use. I was able to message them on a Sunday and get the ball rolling to fix an issue.

I can’t say enough good things about the MonsterApp team. I had a very specific need that, honestly, felt like it would require a brand-new feature. Instead of brushing it off or giving me the usual ‘that’s not possible,’ they jumped in, listened, and actually made it happen. And the best part? They moved FAST! Way faster than I expected. It honestly felt like they built a custom solution just for me. That level of effort and dedication is rare, and I really appreciate the way they went above and beyond.

That’s a wonderful app. I’ve seen other apps that are not as fast and are very heavy to run. This one is amazing, especially because of the kind of support they provide.

At BauUniverso™, we move fast — and so do they! I had a technical issue on my store that needed urgent attention. The MonsterApps team jumped in immediately, diagnosed the problem, and fixed it in just a few hours. Not only did they solve the main issue, but they also double-checked that all colors, sizes, and features were perfectly updated and running smoothly. Their communication was crystal clear, fast, and human — something you don’t often find in tech support. In an industry where delays are common, MonsterApps stands out for their speed, skill, and genuine care for their clients. They didn’t just meet expectations — they went beyond. Highly recommend them to anyone who values reliable, proactive, and high-quality support. Thanks again, MonsterApps — I’ll be recommending you every chance I get! — Founder & CEO — BauUniverso™

Probably the most prompt and thorough app support I've ever received.
