Kolorspun review for Amp Slide Cart Upsell Drawer

Highly recommended, best Cart app I've seen and great support. The cart is much better than the default Shopify cart page, and I benefited from features I hadn't even realized I wanted like the in-cart up sells, which helped increase our average order value. I needed some help at one point with a minor display compatibility issue, and got a response with a solution within a couple of hours.
