SDB ‑ On Sale Discount Blocker

Protect your margins by controlling what discounts can be used during checkout.

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.

• Block discount codes on sale items automatically using compare-at pricing
• Block automatic disocounts on already discounted items
• Prevent unintended discount stacking/abuse and margin loss at checkout
• Protect promotional pricing while still running flexible marketing campaigns
• Easy setup with a lightweight dashboard to manage discount rules
