It should be noted that petshop 4.0 allows anonymous users to use the shopping cart and intention list for shopping without logging on to the site. Log on to the site or register as a user when the shopping is closed for checkout. This feature provides great convenience for anonymous users.

 
Manage the shopping cart and intention list

Items to be purchased can be stored in the shopping cart and intention list. The shopping cart contains the items that the user will pay. The intention list only contains the items that the user intends to purchase, rather than the items that the user actually buys. The items actually bought are stored in the shopping cart. When a user finishes the checkout, the user actually checks the items in the shopping cart, rather than the intention list. Figure 18-9 and Figure 18-10 show the management page of the shopping cart and intention list.
