Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCartStar replaces your theme's cart with a slide-out drawer: recommendations, a progress bar toward free shipping, free gift, and discounts. Gifts run on a Shopify Function, so nobody reaches the threshold by adding the gift itself. After checkout, one more offer can charge the same card, so what a shopper accepts joins the order they just placed.
Encore shows product recommendations at the moments shoppers are most likely to add something: on the product page, in the cart drawer, during checkout, and immediately after payment. You build one customer journey and choose which recommendation appears at each stage, with rules that decide who sees it. Discounts apply automatically to the selected item.
