An item group is any product group in which the items it contains are sold together as a set. This can be set up in a number of ways.
Components are items which must all be purchased together, for example a set with a desktop computer tower, monitor, mouse and keyboard, are set up as components. If the customer purchases the product, the customer receives all 4 items in the product.
All items in the group are sold as a set, and the product group has a price.
Options are items which may or may not need to be purchased together, for example a bundle deal where one or more of the items are not required.
These items are sold together as a set but one or more items are optional. The group may have a price but the contents are configurable.
Separates are items which may not share many attributes but may be part of the same range, for example a new celebrity clothing line for a particular brand.
Each item is sold separately, the group serves to hold content that relates to the whole group and has no price of it’s own.
