PURPOSE:To make the combined discount of plural commodities group to plural commodities group possible by letting a combined discount table and commodity data on a commodity master have a combined discount number, and designating discount data by the combined discount number. CONSTITUTION:When a commodity code is inputted from a POS terminal, the commodity master 5 is retrieved by the commodity code. Then, a record in the combined discount table 6 is retrieved by the combined discount number in the corresponding record, and further, the discount data in said record is retrieved by a constitution number. After the discount data is obtained, commodities of every constitution number are counted in a program, and when they reaches materialized number, the discount is considered to have occurred. Thus, since the combined discount number becomes applicable to a large number of the commodities, the combined discount of a pair of the commodity groups consisting of plural kinds of the commodities respectively becomes possible. |
