What is a cyberspace version of the metal cart you wheel around a store and fill up with merchandise?

The cyberspace version of a metal cart is a virtual shopping cart, used on e-commerce websites. Shoppers browse through digital aisles, adding items to their cart by clicking buttons, similar to placing physical items in a store cart. Once they've selected their desired products, they can proceed to checkout to complete their purchase online. This digital cart streamlines the shopping experience in the virtual marketplace.
