Advanced Fixed-Size Bundle Discount Builder

88% Confidence Medium Market Hard Difficulty $5k-15k MRR Updated May 17, 2026

The Opportunity

A Shopify app for merchants who need strict bundle quantities like 3, 6, or 9 items, with automatic pricing logic that only applies when the exact bundle size is met. It would support mix-and-match bundles across collections while preventing extra items from being discounted beyond the intended bundle size.

"Shopify native discounts do not reliably enforce fixed bundle counts and can keep discounting additional qualifying items instead of stopping at the intended bundle size."

Detailed Analysis

Proposed Solution

Provide rule-based bundle logic with exact-quantity enforcement, collection-based eligibility, and discount application limited to the correct number of items in each bundle.

Target Audience

Shopify merchants selling multi-SKU bundles, mix-and-match sets, or collection-based promotions.

Competitive Landscape

Bundler by Goldendev, WideBundle, All in One Automatic Discount

Implementation Notes

Need cart-level validation and discount engine logic that can track eligible items across multiple collections, enforce exact bundle sizes, calculate lowest-priced-item discounts, and remain compatible with cart drawers and automatic discounts. Must handle theme compatibility, AJAX cart updates, and edge cases where quantities change after discount application.
