Customer service was great. I had some issues when I changed my theme on shopify, Angelica was really helpful and was able to fix it within a day.
— Scott Seafood
Fantastic - support is so helpful and cart is easy to set up and manage. I use it for bundles and one tick upsells. HIGHLY RECOMMEND
— Shoot!
Great app and very responsive support, we recommend!
— Ziji The Label
Really helpful and quick customer service. They were happy to go out of their way to help check the settings were correct when I had campaigns running in several different countries and run an IP address for me to view the different countries. Only took a few minutes for them to confirm everything and send me screenshots

Thank you Angelica for promptly helping me with our query

Just installed today and love it so far! Customer service has been 11/10!
— Margarita Margarita
Works like a charm and their support is the best!
— Wyoming Towel Collective
Really happy with Monster Cart so far. It’s easy to set up, highly customizable, and gives us a lot of flexibility with upsells, free gifts, and cart offers without making the experience feel cluttered. Everything works smoothly with our store and it’s been a great tool for improving the cart experience and increasing AOV. Definitely recommend it!
— Arber
The support from the Monster Cart team is second to none. Would highly recommend the app
— BARE Leather
Helped resolve 2 of our cart issues: adding a custom message for those who add multiple subscriptions, and when the cart suddenly stopped working when adding the first item on our new landing pages.
— The Kindness Company
This app was great until I saw that they were charging me more than double what I agreed to. I want all of my money I have ever given over what I agreed to (14.99) refunded. I just coded my own version of this app and it is way better.
— Maybe Today NYC
Terrible app. I was a client for quite a while and wish I had tapped out sooner. We experienced multiple bugs and glitches that the team repeatedly approached with bandaid fixes, only for the same problems to return soon after. These issues ended up costing us a significant amount in lost sales, as many of them directly affected the cart, including items duplicating in quantity or the cart freezi...
— INFRAHEAL
Been using for about 4 months, many bugs and errors that lead to abandoned carts. Error when using several currencies. Poor support, quick but not very helpful.
— EI CEDO
App is blocking the zoom feature on my store from working on mobile. I found this out by disabling all app embeds and restoring them one by one, testing the zoom feature each time. When I enabled this app, the zoom feature went away again. Reached out to customer service and that was useless. Decided to uninstall the app and found a free alternative while searching.
— Flour Covered Home
Doesn't attribute sales. Meaning I have no idea if the app is driving any value. 'just trust me bro' is a bad value proposition
— DeadEyeVR
The discount calculation is weird and shows up differently in check out. I had so many customers asking. The App has lots of bugs and a very bad support. I moved to Unicorn Cart eventually.
— Magic T
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!
— Bling My Ride
I canceled the plugin, but they still charged me on my monthly bill. I emailed them requesting a refund, but they haven't responded for five days. I was considering whether to reinstall it in the future, but their attitude has left me disappointed.
