About the PromoLock: Discount Blocker
PromoLock gives you complete control over how discount codes work at checkout. Block or allow specific codes site-wide or by pattern, prevent code stacking, and stop discounts from applying to sale items. Build your own profit-protecting offers with built-in fraud guards and redemption limits. The app catches repeat users trying to abuse codes with new identities and blocks them automatically. Track real margin impact for every discount — not just revenue, but actual costs including sale loss and stack loss. See per-code breakdowns to understand which promotions hurt your bottom line. Protect your margins while running smarter promotions with gift card controls and pattern-based rules.
