Great app, works well and the team are very helpful if things are not working quite right. Helped diagnose an issue that affected checkout that wasn't a Monster Cart issue.

love working with monster! theyre the best and have a super responsive CS team!
— Brunae Body
Incredible support from the Monster Upsell team. They go above and beyond to customise our cart and ensure we are happy with the overall features and functions.

Great, easy to use app for upsells. We use the functionality to offer free gifts when customers hit a certain order threshold. When I run into issues, the customer support team is swift to answer and action. 5 stars!
— Bias
WHAT AN APP! So useful and you can instantly see the benefits from an upselling perspective. What is so great is that the team are constantly upgrading and thinking of new methods and ideas to boost your revenue on the cart. The customer support is truly exceptional, even getting replies to chats on Sunday and the team are also open to implementing ideas if good, so one of ours is even on the road...

Fast and helpful support! I reached out to the support team and got a quick response, they helped me smoothly. Very complete app for managing upsells, free gifts, and cart discount thresholds — recommended for anyone looking to increase their store's AOV

great service

Unfortunately, I’m very disappointed with both the Monster Cart app and the customer service. The app is marketed as an upsell solution, but it does not support true tiered upsells. For example, we wanted to offer one upsell when a customer adds a product to the cart, and then unlock an additional offer when they add the first upsell. This type of tiered setup is not possible, which was a major l...

Updating my review as it's only fair. We did have an issue with our billing, but Ty has since reached out personally, resolved it, and genuinely went above and beyond to help. He stayed in touch throughout the process, explained everything clearly, and the customer service has been excellent. We're still using the app and it's been working well for us. Thanks again, Ty, for all your help! Origi...

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...

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.
— polymerholster
unfortunately support is ghosting me and is not answering to any of my tickets. App stopped working and 20% of orders are not discounted.
