Stackable runs volume discounts, quantity breaks, tiered and bulk discounts as native Shopify Functions, so the discount is computed at checkout and the cart total matches checkout, Shop Pay, Apple Pay and Google Pay. Count quantity discounts per product, not per collection. Stack discounts with full combination control. Run BOGO, buy X get Y, shipping discounts and cart discounts. Schedule flash sales, pause anytime, and test any cart before publishing. Uninstall leaves your store untouched.

• Discounts apply the same in cart, checkout, Shop Pay, Apple Pay and Google Pay
• Test any cart to see which discounts apply before you publish
• Pause, resume or reschedule any campaign, with nothing left behind on uninstall
