About the PromoLock: Discount Blocker
PromoLock gives you complete control over how discount codes work at checkout. Block or allow discount codes site-wide or by specific patterns, prevent code stacking, and stop discounts from applying to sale items. Create your own profit-protecting discounts with built-in limits and fraud guards to safeguard your margins. The app catches repeat redemptions from the same customer using different identities and blocks them at checkout. Track the real cost of every discount — not just revenue, but actual margin loss including sale loss, stack loss, and detailed per-code breakdowns. Manage gift cards alongside discount codes to maintain full control over your promotional strategy and protect your bottom line.
