Cheapest Free BOGO Pro
The Opportunity
Create true mix-and-match Buy X Get Y promos where the cheapest item in every group of three is free. Works across products with different prices, supports multiples (3, 6, 9), exclusions, scheduling, and clear in-cart messaging.
"Merchant cannot set up a Buy 2 Get 1 Free deal where the cheapest of three mixed products is free; most apps force a gift workaround that doesn’t handle varied prices or flexible eligibility."
Market Validation
Detailed Analysis
Proposed Solution
A rules-based promotion engine using Shopify Functions to identify cheapest eligible items in groups of three and apply precise product-level discounts, with an admin UI for eligibility rules, caps, scheduling, and analytics.
Target Audience
Shopify merchants running mix-and-match promotions, especially apparel, beauty, and CPG stores with multiple SKUs at different price points.
Competitive Landscape
Bold Discounts, Discount Ninja, Selly, Ultimate Special Offers (Orbit), Bundler, Fast Bundle, Shopify Automatic Discounts
Implementation Notes
Implement discount logic with Shopify Functions (product discount) to select cheapest items in every set of three; maintain rules (eligible collections/SKUs, exclusions, per-order caps, multiples, scheduling) in an app backend with a Polaris admin; surface messaging via Checkout UI Extensions and cart line item annotations; handle variant-level eligibility and tie-breaking deterministically; support prioritization when multiple promos exist; cache eligibility to minimize Function payload size and ensure fast evaluation; add analytics for redemptions, AOV lift, and cohort performance.
