  • Block or allow discounts and gift cards, site-wide or by pattern
  • Create margin-safe discounts that grow revenue — one code or bulk
  • Catch repeat redemptions — same customer, new identity, blocked at checkout
  • Stop code stacking and discounts on already-marked-down items
  • Track the margin bleed behind every discount you run

Block discounts by code or rules, build profit-first offers, analyze & fix losses on top codes.

PromoLock rules how discount codes behave at checkout. Block or allow discount codes site-wide or by pattern, stop codes stacking, and control discounts on sale items. Create your own discounts with the limits and fraud 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.
