Smart Discount Rule Builder for Buy-X-Get-Y Order Sequencing
The Opportunity
Merchants want discount logic that can target the second item added to cart, not simply the cheapest item. An app could provide flexible Buy X Get Y rules based on cart order, product priority, collections, or custom ranking.
"Shopify’s native Buy X Get Y logic discounts the cheapest eligible item, which breaks merchant promos that depend on the item added second or on a specific cart sequence."
Market Validation
Detailed Analysis
Proposed Solution
Build an app that lets merchants define advanced discount priority rules: second-added item, highest-priced item, lowest-priced item, specific collection, specific SKU, or custom item ranking. Apply discounts through Shopify Functions/discounts with clear preview behavior in cart and checkout.
Target Audience
Shopify merchants running promotions, bundles, flash sales, and mix-and-match offers
Competitive Landscape
Discount Ninja, Automatic Discounts apps, Bold Discounts, simple bundle/BOGO apps
Implementation Notes
Use Shopify Functions discount logic to rank eligible cart lines by add sequence or configured priority. Store rule settings in app admin, surface a preview of how items will be discounted, and handle edge cases like quantity changes, reordering, and multiple simultaneous promotions. If exact add order is unavailable in some contexts, provide deterministic merchant-defined fallback priorities.
