About Discount Guardian

Running a 20% off sale and worried customers will stack another code on top? Selling gift cards that shouldn't be discounted at all? Discount Guardian blocks specific codes on the products, collections, vendors or locations you choose and shows shoppers a custom message at checkout so you don't kill the sale, just the discount. One click pauses every discount code site-wide during a flash sale, then reactivates them just as fast. Works alongside your existing discounts. No theme edits Block or cap discount codes for products, variants, vendors, gift cards and more Set custom messages about why a discount code is blocked so you don't lose sales Prevent discount codes being used on products that are on sale Block all discount codes on checkout with a click & reactivate as easily Show more Show less
