I've been told for over a year that in-cart upsells are where it's at, and I've ignored it, thinking it would be too hard to set up. I finally dove in to search for an app, and landed on this one. EXTREMELY easy to use - they walk you through so many best-practice options a tips. I had it set up in an hour. Better yet - nearly every order for the entire next week used it. The psychology of "buy one, get more" is crazy powerful. Our AOV jumped instantly. Crazy awesome support, super friendly and fun. Totally use this app.

Amazing customer service. Ty has been super service oriented, and suggested some best practices to get us off to a good start. I'm looking forward to seeing how this pans out, and will be tracking our AOV closely.

I use this app to offer gifts and incentives to customers. The extension works like a charm and support is great.

Easy to set up and quick customer service that is not a robot! We will be using this for the first time this week and we will see how much more revenue it helps on our orders.

This app destroys my conversion rate. Due to this app customers can't reach Cart and checkout pages...

You have misunderstood what the app does!!! 😅 😅 😅
Your theme has a cart drawer that needs to be turned off! (see your video)

We have 1000's of stores that use the app perfectly.
Please reach out to the support team if you don't know how to do this.

1000% guarantee the problem can be easily fixed and it's only related to your theme.
