CartServe: Cart Drawer Upsells

CartServe replaces your standard Shopify cart with a slide-out cart drawer that you can customize without any code or theme changes. The no-code drawer builder lets you drag and drop blocks and preview everything live on real products before publishing. Add reward goals like free shipping thresholds or spend tiers with a progress bar that updates as customers shop. Shoppers can apply and remove discount codes directly in the cart drawer without leaving. You can also offer opt-in shipping protection that customers add themselves right in the drawer. The app installs on your existing cart button and includes fail-safe protection - if the drawer doesn't load, your theme's default cart takes over automatically. Your checkout is never blocked, so customers can always complete their purchase.
