Boost AOV with quantity breaks and product offers on your storefront.
SellApp helps merchants increase order value with quantity discounts and product page offers. Merchants set discount tiers per product, such as buy more and save more, and the discount applies automatically at checkout. A theme app extension shows the offer on the product page so customers see the deal while shopping. Offers are managed from the Shopify admin without custom theme code. This reduces the need for discount codes and makes volume pricing easy to set up and update.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows SellApp on a store, it is there.
