About the CartRules

CartRules helps merchants protect profit margins and prevent discount code abuse by blocking codes and setting quantity limits on specific products, tags, or collections. Create rules in minutes to control which products customers can apply discounts to and cap maximum order quantities per item. Display custom messages on product and cart pages explaining why limits apply, keeping customers informed throughout their shopping experience. When multiple rules affect the same product, the app automatically applies the most restrictive limit to eliminate conflicts. No coding or theme editing required—simply select products by tag or collection and set your rules. Perfect for merchants who need to maintain pricing integrity on premium items, prevent bulk buying abuse, or exclude certain products from promotional campaigns while still offering store-wide discounts.
Launched: October 12, 2026
