Precautions:

The shopping cart mentioned in the online store is self-evident to the real shopping cart. Buyers can add and delete goods at will just like shopping in a supermarket, and place orders in a unified way after purchasing.

Shopping carts in online stores should be able to track the goods selected by customers, record the selected goods, update them at any time, pay for purchases, and provide great convenience to customers.
