A shopping cart is a wheeled container used by customers in stores to carry their items while they shop. Typically made of metal or plastic, it allows shoppers to easily transport groceries, clothes, or other products from the aisles to the checkout counter. Shopping carts come in various sizes and designs, including those with child seats for parents shopping with kids. In recent years, many stores have introduced online shopping carts on their websites. These digital carts let customers add items to their virtual basket while browsing online. Once they are ready to purchase, they can easily check out and have their items delivered or prepared for pickup.
