Monster CartUpsell — Free Gift

Charlene was very helpful and easy to chat with. Made my experience with Monster Cart seamless, highly recommend.

Angelica, was very helpful and fast reponding. Nice support!

I can’t recommend the Monster Checkout Cart app enough! It’s incredibly customizable, easy to use, and integrates seamlessly with my Shopify store. What really sets it apart is the customer service — they respond so quickly and go above and beyond to help with any questions or tweaks I need. I love how flexible the app is, and it has made a huge difference for my store’s checkout experience. Truly impressed and very happy with both the app and the support team!

Very quick and responsive. I really enjoy working with them and their support staff.

The Monstercart upsell app looks amazing. I'm currently still going through setup, and have had an incredible experience with support helping me through some of my initial setup already.

Excellent experience with customer service team (Angelica in particular). Responses are always prompt and they've been very helpful in getting the cart to show on our site!

This app has great features and the best customer service I have ever experienced! Super fast replies and they always go above and beyond to solve any problems.

Great app great customer service have been using for years never looking back

Very helpful customer service, they helped me 2 separate times in 2 days both times they solved the issues in no time at all. The first was integrating the Shopify cart to monster as the shop cart icon to avoid confusion and the second was helping resolve an issue with my gift tiers. Thanks team!

I've always had such an amazing experience with Monster Upsell. The customer service team are swift with their replies and so helpful. Charlene is fabulous. A super easy app to integrate into your store. Highly recommend

Angelica was very helpful in troubleshooting and fixing up the issue when we had trouble setting up the free gift offer. Response time is very quick and she was able to get it sorted in no time.

A great app for managing your carts with specials such as free gifts, discounts and campaigns. Their support channel is usually quick to reply and the team is very friendly and eager to help

Great customer service, very quick to reply and they have all the answers. Charlene in particular was very helpful, thanks!

So far we're loving it! We had a minor issue with a gift with purchase promotion we were running but the issue was swiftly resolved by the customer service team and our campaign was up and running asap.

amazing customer support. Really good app to increase AOV

Such a game changer! Love the simplicity and effectiveness of this app - also the support team were really fast to solve my issues during set up!

Monster Cart Upsell is by far the smoothest experience I’ve had on Shopify. The setup was almost too easy – it literally took me just a few minutes to get it up and running, with no need to mess around with code or complicated settings. What really blew me away was the customer support. I had a small question about customizing the design, and their support team replied almost instantly – super friendly and helpful. They provided clear guidance and helped me get everything just the way I wanted. The cart itself? It looks amazing. Super modern, clean, and very detailed – everything from product add-ons to discounts and custom messages blends perfectly into the cart design. My conversion rate has already gone up, and the whole shopping experience feels much more premium for my customers. If you're on the fence – just install it. You won’t regret it. – Happy store owner

Very strong customer service and prompt response
