A shopping cart is a wheeled cart used by customers in stores to collect and transport items they wish to purchase. It typically features a large basket for holding products and a handle for easy maneuvering. Shopping carts are commonly found in grocery stores, retail shops, and online shopping platforms, where they serve as a virtual tool for selecting items. In online shopping, a digital shopping cart allows users to add products to their selection before proceeding to checkout. This feature helps customers review their choices, adjust quantities, and calculate total costs. Many e-commerce websites, like Amazon and eBay, utilize shopping carts to enhance the shopping experience.
