Cartwise

Cartwise helps merchants raise average order value by turning the cart into a place to sell more. You can build product bundles, set quantity breaks that reward larger orders, offer a free gift at a spending threshold, and let customers mix and match items. A built-in cart drawer shows these offers while shoppers browse, and post-purchase offers appear after checkout. Setup uses pre-built templates, so you can launch offers without writing code or editing your theme.
