EB Stack Discounts

Shopify normally applies only one discount per class (product / order / shipping). EB Stack Discounts lets you run a second offer — a percentage off or Buy X Get Y — in a different discount class, so it automatically combines with a discount you already run. Enter your existing discount, pick your offer and products, and the app handles the class selection and "Combines with" settings for you. No theme edits, no Plus plan, no customer data collected.
