CartOn replaces your theme's cart with a slide-out drawer you control from one editor. Set spend tiers that unlock free shipping, a discount or a free gift — CartOn creates and maintains the Shopify discount, so the reward really applies at checkout. Add in-cart upsells, a countdown announcement, discount code field, order notes and trust badges. Offer shipping protection priced as a share of the cart, updating as it changes. Works on most themes with no code, and reports the revenue it earns.
