A method of processing a retail transaction includes processing a plurality of items for purchase using a point-of-sale terminal, which is part of a transaction approval system at a point of sale in a retail store. Processing the plurality of items includes using the point-of-sale terminal to determine associated price information for each item. Processing the plurality of items begins when information regarding an identifier of a first one of the plurality of items is entered into the point-of-sale terminal and ends when the information regarding the identifiers associated with all of the plurality of items has been entered into the point-of-sale terminal. The method further includes, before processing the plurality of items ends, electronically receiving an identification of a financial account to pay for the plurality of items, and after electronically receiving the identification of the financial account, determining a total cost of the plurality of items.
