Product Protection
Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureDIScide lets merchants define rules for how discount codes interact at checkout. It helps prevent unintended combinations of discount codes that would otherwise be applied together. Merchants can decide which discount codes are allowed together and which combinations should be blocked. This makes discount behavior predictable and reduces the risk of excessive discounts.
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.
- Decide how discounts behave before they affect real orders.
- Decide which discount codes can be used together at checkout.
- Decide how discount conflicts are resolved when multiple codes are entered.
- Decide different discount rules for different markets.
- 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.
