A shopping cart has a similar function to a normal shopping cart or trolley, but it is used online on eCommerce sites. It allows customers to add items to their cart which they can then purchase at an online checkout.
People who visit an eCommerce website (e.g. Amazon) can search products and ‘add to cart’ the items that they either wish to buy now or at a date in the future. It allows visitors to create a virtual list of the products they like which they are not obliged to purchase but can do so if they wish.
Upon checking out, customers are able to select postage details with some websites offering gift wrapping and different levels of postage cover.
There are different companies which offer shopping cart platforms where the cart is integrated into the website and hosted for you. These include Shopify, BigCommerce, Magento, Volusion etc.
