DiscountFence

Stop discount codes stacking on your sale items — without rebuilding a single discount. Free on live stores.

• Works on the codes you already have. DiscountFence sits in front of your native Shopify discounts and refuses them where you say. Nothing gets rebuilt inside another rule builder.
• Real exclusion lists. Refuse codes on sale items, tags, collections, vendors, product types, handles, gift cards or subscription lines, with your own checkout message.
• Free on live stores. Unlimited fences, no usage caps, no trial — and it says plainly what a Shopify function can and cannot do.
