Access to the shopping basket
The shopping basket link or summary should show at least the current sum of products bought. Ideally the customer can see the number of items, product name, price, additional costs such as VAT or shipping/handling fees. Some companies even show the delivery time.

The shopping basket page
Ideally a thumbnail picture of the product is displayed and a short product description, which are both linked back to the product page. (This is helpful, in case the customer comes back at a later point in time and wants to easily review his order). The page needs to summarize:

• The cost per product
• The VAT per product
• The shipping/handling fee
• The total payable fee

The user also needs to be informed of shipping time and links to warranty and exchange policy need to be available.

The customer also needs to be able to delete a product or change the number of products.

Also make sure that the customer has both options: to continue shopping and to check out. This is missing in the Tchibo examle.
