Upsell

The Upsell block is designed to increase average order value by showcasing complementary products that customers can quickly add to their cart—ideally with no variants for seamless one-click purchase.

When selecting a product for the 'buy it with' promotion, we recommend you choose products with one variant.

How to set up

Setting	Type	Description
Info paragraph	paragraph	Highlights that upsell products should ideally have no variants for better performance, as one-click add-to-cart.
Product list	product_list	Select up to 3 products to feature in the upsell carousel. Use the theme.upsell_list metafield for dynamic content.
Cart info paragraph	paragraph	Describes how to use a dynamic source (theme.upsell_list) to carry upsells into the cart. Custom metafield names will limit upsells to the product page.
Appearance info	paragraph	Explain that appearance settings can be adjusted under Theme Settings → Upsells.
Padding bottom	range	Adds space beneath the block (0–50px, adjustable in 2px steps).

Select the upsell product. It will only be displayed on the product page.

You can also use a metafield namespace and key 'theme.upsell' to allow product upsells to follow users into the cart.
