An
electronic commerce tool (
software
or service) that is the
user-interface for the customer to shop at online stores. It allows users
to place items in a "shopping basket", and the cart remembers these
items for a predetermined length of time. Extra features such as different color or size options, quantity of
order, and matching item links can be found linked from the shopping
cart. Once a shopper inputs his shipping address, taxes and shipping
costs can also be tallied from within the shopping cart. For the
merchant, the shopping cart also provides important information, which
is often transparent to the shopper including a cart number to track the
order, and a cookie to provide you with some limited tracking details
about your customer.
