Monster Cart Upsell+Free Gifts

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.

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!

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.

I’ve been using Monster Cart App for a couple of months now, and I have no hesitation in recommending them. The functionality is excellent, and the app is easy to set up and customise. At first, I was hesitant to try it because I wasn’t sure about the cart design, but that concern was totally unjustified, as you can customise it to look exactly how you want.

What also stands out is the amazing support team. They’re friendly, responsive, and always willing to help, which makes a huge difference.

Looks cool but I kept experiencing huge delays between clicking the cart or adding a product and the cart actually opening. Chatted with customer service twice but they said it was functioning normally. Also ran into issues where items would not add to the cart. Had to stop using it. Not sure if it was my theme because other people seem to have a good experience with this app.
