DiscountHero protects your margins from discount code abuse. It checks every discount code live in the checkout against the code's restrictions and your customer history, and automatically removes codes the customer is not eligible for, most importantly new-customer codes used by existing customers.
New-customer discounts leak. Codes end up on coupon sites and in browser extensions, and existing customers redeem them with a second email address. Shopify's own check only catches the exact same email; anyone using a fresh address walks through. At scale, that is a real margin problem.
Every removal is logged transparently in the Activity Log. Details: How DiscountHero detects discount abuse.
DiscountHero runs as a checkout extension that intervenes in the discount logic, which Shopify only allows on Shopify Plus. On standard plans, the app will not appear in your checkout editor. If you are not on Plus, DiscountHero is unfortunately not available for your store.
Follow the Setup guide (installation, checkout extension, order import) and configure your discount codes correctly (How to set up your discount codes correctly).
