Advanced Fixed-Size Bundle Discount Builder
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."
Market Validation
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.
Evidence from Merchants
Real quotes from Shopify community forums
"Seeking a Shopify bundle/discount solution that can handle: fixed bundle multiples (3, 6, 9 only), mix-and-match across multiple collections, discounting the lowest-priced eligible items, compatibility with cart drawers, and allowing discount codes alongside automatic discounts."
"Shopify’s native discount tools were described as insufficient because they keep discounting extra qualifying items beyond the intended bundle size."
"These requirements are unusually complex, especially the 'discount the lowest-priced item(s)' rule."
"A more advanced path was suggested: custom development, Shopify Plus scripts, or automation tools like Mechanic to apply custom discount logic."
"Simple Discounts was the strongest match claimed in the thread: exact bundle counts, up to 8 collections, mix-and-match, and lowest-item discounting."
Key Pain Points
Insufficient native discount tools leading to unintended discounting of extra items.
