Create discounts that protect margin. Measure what slips through. Block what bleeds you.
PromoLock rules how discount codes behave at checkout. Block or allow codes site-wide or by pattern, stop codes stacking, and control discounts on sale items. Create your own discounts with the limits and abuse guards to protect your margin. See the exact margin each discount costs you, not just the revenue it brings — sale loss, stack loss, and per-code breakdowns.
- Create discounts built to grow revenue without giving away margin
- Block or allow discounts and gift cards, site-wide or by pattern
- Stop code stacking and discounts on already-marked-down items
- Track the margin bleed behind every discount you run
- Show localized error messages when a code is rejected

works perfect and absolutely needed on every shopify site for black friday or other site markdowns. only issue is how hard this was to find in the shopify app store.
Thanks so much for the great review! I’m glad PromoLock works perfectly for your store, especially during big sales.
