Shopping Cart in Online Store: Overview of Methods

The shopping cart is a temporary storage area where customers add products and services they intend to purchase. In the cart, customers can adjust the quantity of items, remove unwanted products, and view the total cost of their purchase. When the customer completes the purchase, the cart is linked to the order.
