Product Protection
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSet checkout guardrails for promotions without editing your theme. The app rejects eligible conflicting discount codes and blocks checkout when final line amounts violate a published rule. Create storewide or targeted safeguards, set minimum final amounts or maximum markdown percentages, protect sale items from additional discounts, add country and buyer exemptions, and preview outcomes in the simulator.
Ever run a 20% off Black Friday sale, only to realise a customer used it on a premium product with a 10% margin? Margin Defender is your failsafe! Margin Defender prevents you from accidentally discounting premium items that should never be on sale. Simply tag specific products as "protected," and this app will block checkout if any discount code is applied while those items are in the cart.
- Block discounts that push final prices below a set floor
- Cap total markdowns with maximum discount percentages
- Protect sale items from additional discount stacking
- Target rules by product, variant, collection, country, or buyer
- Exclude specific products from store-wide sales so you never sell at a loss
- Automatically block checkout if a protected item has a discount applied.
- Works seamlessly with both discount codes and automatic promotions.
- Failsafe design ensures checkout always works, even if validation times out.
