Monster Cart Upsell+Free Gift

I would rate this 10 stars if I could. This is by far the strongest cart upsell app on Shopify right now.

Since implementing it, I have doubled my AOV, and it includes every feature you could need in a serious upsell tool. For a while I was torn between OCU and Monster Cart, but with their latest updates, Monster Cart clearly wins across the board.

Customer support has also been excellent. Fast, reliable, and at one point I even had one of the founders, Ty, personally assisting me.

100/10. If you are looking for an upsell app that genuinely lifts AOV, this is the one to use.
