Bundle substitutions

Use a separate list of backups when the sold-out variant is sold inside a bundle.

Available on the Growth and Scale plans.

How it works

A rule can have two lists:

• Regular orders: used when the variant is bought on its own.
• Bundle orders: used only when the variant is part of a bundle.

The two lists are separate. Bundle orders never use the regular list, and regular orders never use the bundle list. Only the sold-out item in the bundle is swapped; the rest of the bundle ships as ordered.

Set it up

1. Open the rule and add at least one substitute under Regular orders. Bundle substitutes work alongside your regular list.
2. Under More options, turn on "Use a separate list when this product is sold inside a bundle."
3. Under Bundle orders, click Add a bundle substitute and pick the backups.

Why a regular list is required

Turning on the rule lets the variant keep selling when it's out of stock. Shopify can't tell a variant sold alone from one sold in a bundle, so the variant keeps selling in both. The regular list makes sure orders for the variant on its own are covered too.
