Shopping Cart

Shopping cart and item management

What it solves

A Shopping Cart pattern helps teams create a reliable way to give shoppers a safe place to review, edit, and validate an in-progress purchase before paying. It is most useful when teams need cart review before checkout. Compared with adjacent patterns, this pattern should reduce friction without hiding the state, rules, or recovery paths people need to keep moving.

When to use

• Cart review before checkout
• Editing quantity and variants
• Persistent carts across sessions
