A bundle is a kit item that consists of many components. A bundle's components can be products, provided services, physical kits, or other bundles. However, a delivery service cannot be a component of a bundle.
The inventory for a bundle is maintained at the component level. Inventory tags can be given to a bundle, but they are ignored by the application.
The item Bedroom Set, which includes the components Bed Set, Dress Set, Entertainment Set, and so on, is an example of a bundle. The Bed Set, Dresser Set, and Entertainment Set can in turn, be individual bundles by themselves.
