The Shopping Cart is part of WebGUI Shop. WebGUI Shop allows users to sell online merchandise, sell subscription services, collect online donations, and sell access to and manage events.

The Shopping Cart has been designed to be user-friendly. Users enter shipping and billing addresses, and Shop will store those addresses for the user to select from again. Items are easily removed or increased in number, and totals updated.

A number of macros are also available to customize how users access their carts, including a mini cart view that allows users to see how many items are in their carts and the total purchase price while they shop. In-store credit can also be given, which is applied to items placed in a shopper's cart at check-out.
