Unlimited Mix-and-Match Buy X Get Y Discounts
The Opportunity
A discount app that replicates Shopify’s automatic Buy X, Get Y behavior but removes the 100-product limit and supports large catalogs. It would let merchants run mix-and-match promotions across products and variants, automatically discounting the cheapest eligible item.
"Merchants want native-style automatic BOGO or 3-for-2 promotions across more than 100 products, including variant-level eligibility and mix-and-match behavior."
Market Validation
Detailed Analysis
Proposed Solution
Build a Shopify discount app using Shopify Functions that supports large product sets, variant include/exclude rules, and automatic cheapest-item selection for Buy X Get Y promotions.
Target Audience
Shopify merchants with large catalogs running promotions across many SKUs or variants, especially apparel, beauty, consumables, and multi-variant stores.
Competitive Landscape
Discount Ninja, BOGOS, Automatic Discounts by Appikon, Bundler, WideBundle, PickyStory
Implementation Notes
Use Shopify Functions for discount logic, support variant-level eligibility lists, large product selectors, automatic cheapest-item discounting, cart validation, and admin UI for mix-and-match rule building. Add safeguards for multiple currencies/Markets and performance testing for large collections.
