VbzCart/docs/pieces/cart

A cart is a temporary holder for a collection of items to be ordered plus any order-fulfillment data (contact/shipping info, payment). The contents of a cart may be used to create a new order, or may be abandoned. They cannot currently be added to an existing order, although this might be useful functionality.

Code

Cart functionality is defined in:
