Upsell related products on a product's details page.

Add-ons are existing products from your store that show as an optional extra purchase when customers view another product's details page. For example, if you sell plants, you can offer a ceramic pot as an add-on to a houseplant. If you sell classes, you can offer a workshop as an add-on to a class series.
