PromoLock lets Shopify merchants instantly block the use of all discount codes and gift cards at checkout. Quickly pause promotions during sales, maintenance, or policy updates—no need to edit or disable each code individually.

• Disable discount & gift card usage at checkout

A code made for one newsletter or influencer has a way of ending up on RetailMeNot and in extensions like Honey, where every shopper gets a unintended discount. LeakHunt scans coupon sites daily for codes from your store and lists only those still active, so you see real exposure, not noise. Get an email when a new leak appears, disable it in one click, and whitelist codes you share on purpose. Coupon extensions are blocked from applying codes at checkout. It only needs access to discounts.
