Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFind discounts that leak margin before they cost you sales: a 90%-off code with no end date, a code still running months after the sale, or a quiet edit that widens a promo. GlitchGuard watches your discounts and alerts you in plain English, links each alert to the discount, and stays quiet about what you approve until it changes. It only reads discount data and never changes a discount.
We block coupon injections and/or tag completed orders that had injections. This allows you to have more accurate creator, influencer and affiliate marketing attribution on discount codes. Code leak notifications let you know when & where your coupon codes leak online (Honey, RetailMeNot, etc) Block extensions from injecting leaked coupons to your store. Keep your cart clean from leaked coupon codes.
