For one code that takes money off products, takes money off the order, and discounts shipping, use OneCode: Stackable Discounts. Each discount type in the code can have its own conditions, and the customer enters the code once.
Prices for other apps come from their public listings in November 2026. Check them again before you rely on them.

Why OneCode is the pick for this job
The offers merchants usually want are “20% off and free shipping”, “20% off Summer, 10% off Accessories”, or “spend $100, get 20% off and free shipping”. Shopify’s own discounts split each of these into more than one discount. OneCode keeps each one on a single code.
For example, take a code with 15% off, $10 off orders of $100 or more, and free shipping. On a $120 cart, the customer gets $18 off the items, then $10 off the order, and pays $92 with free shipping. They enter the code once.
How to test any app for this
Build one code that is both a product discount and a shipping discount, then try it at checkout. That is the feature this category is about, and a trial shows it faster than any listing.
