Prepaid-only discount controls

Keep selected discounts away from Cash on Delivery.

PrepayGuard lets merchants mark selected Shopify discount codes as prepaid-only. When a marked code is applied, configured payment methods are hidden; removing the code restores them.

Merchants install and open PrepayGuard through Shopify. If the app is already installed, open it from the Apps section of Shopify admin.
