The use of computers in planning consumer food purchases requires that price estimates for a selection of goods be determined in advance of the purchases. If such estimates are to be widely used, they must be accurate and inexpensive to generate. This paper describes a price estimation method which meets these criteria. The method is intended to be applied to shopping baskets of goods from any store in a community. The results of empirical tests of the method are reported which reveal support for its accuracy and ease of use.
