Margin first
Reject risky discount contexts before they become margin problems.
Shopify discount margin protection
Stop discount codes from leaking margin in risky carts.
Protect sale items, gift cards, subscriptions, B2B carts, and protected products with a focused discount guard built for simple margin control.
Small rule set
Prebuilt guardrails avoid a sprawling discount rules builder.
No cart history
Cart context is evaluated ephemerally and discarded after the decision.
How it works
- Merchant enables the guard and selects protected contexts.
- The checkout discount function evaluates the active cart context.
- If a configured leak condition matches, the code is rejected with the configured message.
- The app stores only merchant settings, billing metadata, and aggregate usage counters.
Zero sensitive data storage
Merchant discount guard settings, billing metadata, aggregate monthly counters, and non-sensitive technical status.

No. It protects risky contexts around discounts; it is not a promotion builder.
Does it store discount attempts?
No. The MVP stores settings and aggregate counters only.
