We run an e-commerce store on Shopify (Grow plan) and we display a “before price” / original price on some products. However, these products are not treated by Shopify as discounted products, because Shopify does not recognize our current “before price” setup as a native sale price (i.e. it is not using Shopify’s standard sale price logic for discount eligibility). As a result, customers are currently able to apply discount codes on top of already discounted products, leading to unintended double discounts. Current situation: Shopify Grow plan (not Plus) Products have a visible “before price” / original price Shopify does not treat these products as “on sale” in its discount logic Discount codes can be applied to these products (problem) Goal: Prevent discount codes from being applied to products that already have a discounted price The solution must work within the limitations of Shopify Grow (no Shopify Scripts) Preferably an automated and low-maintenance solution for our team What we’re looking for: A technical solution to block discount codes for already discounted products The solution can be based on Shopify-native features (collections, tags, metafields, product flags, etc.) or a clean workaround Clear guidance on how our team should manage sale products going forward Optional: recommendation on best practice (e.g. whether switching to Shopify’s native “Compare at price” setup is advisable) Deliverables: Implementation in our Shopify setup Short documentation / instructions for non-technical users Explanation of limitations and edge cases
