Abstract: A shopping system for purchasing one or more goods comprising: at least one shopping cart into which items to be purchased are placed. The cart includes a quantity measurement mechanism to detect a measureable quantity parameter (e.g. weight or volume) of each good placed in the cart. The system further comprises a shopping environment in which goods are arranged in designated areas according to their price per quantity parameter; a mechanism for ensuring that goods placed in the cart are associated with the measurable quantity related to the good(s); and a payment collection arrangement.
