About the Margin Defender: Block Coupons
Stop losing money on accidental discounts and protect your profit margins with this essential checkout protection tool. Margin Defender prevents customers from applying discount codes to premium products that should never be on sale.
Simply tag specific products as "protected," and the app will automatically block checkout if any coupon code is applied while those items are in the cart. Perfect for preventing situations like a 20% off Black Friday sale being used on premium products with thin margins.
This app shields low-margin items from coupon abuse so you never sell at a loss. It provides total coverage against both manual discount codes and auto-discounts. The failsafe design ensures your checkout always works smoothly, even if validation times out. The simplest, most efficient way to protect your bottom line from unintended discounts on protected products.
