SKU bundles are SKUs composed of several other SKUs. Bundles allow a group of items to be purchased as a single item but treated as multiple items in order fulfillment. Bundles differ from configurable SKUs in that the component SKUs of a bundle are always the same. For example, a SKU bundle could consist of six #2 pencils and a pencil case.
Creating a SKU bundle is a three-part process:
Create the individual SKUs that the SKU bundle is composed of.
Create SKU links from the SKUs. A SKU link consists of an individual SKU and a quantity.
Create a SKU whose Bundle links property consists of one or more SKU links.
For example, suppose you want to create a SKU bundle that consists of six #2 pencils and a pencil case:
Create a SKU that represents a #2 pencil, and create another SKU that represents a pencil case.
Create a SKU bundle by creating a new SKU that will contain links to the Pencil SKU and the pencil case SKU.
In the SKU bundle, create a SKU link that represents six of the #2 pencil SKUs, and create another SKU link that represents one of the pencil case SKUs.
