Highlight complementary products and encourage customers to add extra items to their order.

Encourage customers to add related or complementary items to their purchase by displaying add-on products. Add-ons are existing products from your store that display as an optional extra purchase when shoppers view another product's details page. For example, ​​if you sell plants, you can sell a ceramic pot as an add-on to the purchase of a houseplant. If you sell art prints, you can sell a frame as an add-on to the purchase of a print.

This is a great way to upsell and increase revenue by helping shoppers find and add relevent products to their orders.
