How to review
01
Check the quantity and total amount for change
Increase the quantity, delete a product, then undo. The price of each line, the number of items and the provisional total must be updated consistently without losing the current viewing position.
EXAMPLES
Usage examples
Delete the wrong product
After deleting an item, it says "Removed from cart" with an "Undo" button; Restore the correct color and quantity selection.
Variants and use cases
Original image from Checklist Design
The shopping cart has many versions
Separate products, versions, quantities and prices so buyers can check the correct item before paying.
Change size or quantity; Total and stock status must be updated together.
Example Two shirts with the same name but different sizes still have two clear lines in the basket.

The food delivery cart is empty
Keeps the delivery location and selected store when the item is not available, bringing the user to the list where they can order.
Delete the last item; Don't keep old totals or clickable pay buttons.
Example “No items in cart” goes with the View current store menu button.
