Creating bundle-based offers such as “Buy 5 for ₹599” or “Buy 2 Get 2” is a proven way to increase average order value and improve product discovery on Shopify stores. However, many merchants rely on third-party apps to implement these offers, which often introduce performance issues, recurring costs, and limited design control. This blog presents a clean, scalable alternative using Shopify’s native Online Store 2.0 architecture combined with a custom collection template. The approach documented here uses a custom bundle collection template powered by a single Shopify section that handles all frontend bundle interactions. This includes product selection, quantity validation, dynamic messaging, and add-to-cart behavior. By keeping all bundle logic on the frontend and delegating pricing and discount calculations to Shopify’s built-in discount system, this setup remains fully compatible with Shopify checkout while avoiding complex workarounds or unsupported logic. A key advantage of this system is its flexibility. Each bundle offer is represented by its own dedicated collection, allowing merchants to create multiple offers with different product sets, quantities, and messaging without modifying code. Design, layout, and typography can be controlled directly from the theme editor, making the solution suitable for both developers and non-technical store owners. This guide walks through the complete implementation process in a structured and practical manner, starting from adding the custom section to the theme, creating offer-based collections and templates, configuring bundle behavior, and finally setting up the required Shopify discounts. By the end of this blog, you will have a production-ready bundle system that is performant, maintainable, and aligned with Shopify best practices.
