DiscountFence: Code Rules

DiscountFence lets you add exclusion rules to your existing Shopify discount codes without rebuilding them. Your current codes stay exactly as they are. Create custom fences using conditions like sale items, product tags, collections, vendors, product types, handles, gift cards, or subscription lines. Apply these rules to all discount codes, specific codes you name, or exclude certain codes from the rules. You control the message shoppers see when a discount code is refused at checkout. The app uses a Shopify Function to handle code exclusions during checkout. Test any cart directly in your admin panel to preview the exact wording and behavior customers will experience before going live.
