Ecommerce Website - The single most important aspect of automating your Web store is using a shopping cart. As this allows the customer to pick and choose what they want to buy and then purchase everything at once. This provides the customer with a 'virtual shopping cart.' They want to buy something, they simply place it in their virtual shopping cart. Later if they change their minds,they can remove the product from their virtual shopping cart. They can purchase the contents of their shopping cart, when they are done shopping.
