Display an upsell product on your page and in the cart.
When selecting a product for the 'Buy it with' promotion, we recommend you choose products with one variant.
Select the upsell product. It will only be displayed in the product page.
You can also use a metafield Namespace and key 'theme.upsell' to allow product upsells to follow users into the cart.
