How do I set up recommended products from related collections to bundle with the main products?

Many merchants want to offer product recommendations from related collections to enhance cross-selling. For example, when a customer views a shirt product, it’s ideal to show complementary items like trousers, denim, t-shirts, and innerwear together in the frequently bought together section.

Currently, using the “Same collection” strategy only displays products from the exact same collection as the main product — in this case, only shirts. This is due to technical and platform limitations.

Recommended Approach

To provide relevant product bundles while maintaining optimal performance, we suggest creating specific bundles for your main products, such as shirts. This approach allows you to:

• Manually select related products to include in the bundle (e.g., trousers, denim, t-shirts, innerwear).

Benefits of Manual Bundle Creation

Manual selection gives you greater control over which products appear together, avoids potential performance issues, and works within Shopify’s current technical framework.
