See every featureRetail Price Discount lets merchants create virtually any promotion from the Compare-at Price or selling price without changing existing catalog sales. Run automatic discounts, codes, BOGO, Buy X Get Y, free gifts, quantity and variant-based discounts, or combine product discounts and free shipping in one code with delivery-address rules.
SDB prevents customers from using discount codes on products that are already on sale, ensuring your promotions do not stack unintentionally and lower your margins. Using Shopify’s compare-at pricing, it automatically blocks coupon codes or automatic discounts when items are already discounted, helping you run controlled, more profitable promotions.
- Apply discounts from compare-at amounts
- Automatic fallback to regular amount
- Prevent stacking with existing catalog sales
- Optional product-level discount targeting
- Stop customers from using discount codes on already discounted products
- Quick and easy set-up, protect your margins almost instantly
- Easy management dashboard for your custom discounts
