How it sells itself

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.

Shopify discounts ignore the compare-at price and stack on items already on sale. Solo Discount fixes it per variant with a Shopify Function. Discount off the compare-at price with a floor, so customers never pay more than your sale price, or exclude sale items from the discount entirely. Works with discount codes and automatic discounts, and combines with your other discounts only when you choose.

Key points
  • 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
  • Respects compare-at prices: skip on-sale variants or discount from compare-at.
  • Variant-level, not product-level — on-sale variants don't block the discount.
  • Native Shopify Function — no theme code, no checkout scripts, no added latency.
  • Automatic and code discounts supported — scope to products, collections, or all.
