About PromoLock: Discount For Growth

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 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 Show more Show less

Very easy to use, is able to turn off and on specific discounts. Has a lot of settings/options to choose from!

PromoLock app is working really well for our needs, and the support team has been great—quick to respond and very helpful. Overall, a smooth and reliable experience.

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.
