To perform sales cooperation among a plurality of stores constituting, for example, a shopping center, a street of stores, or the like. To enable this cooperation, a clerk in each store proposes, to a customer in the store, coordinated commodities in which a commodity for sale in the original store is combined with a commodity for sale in another store. According to the proposal, when the customer comes to the other store introduced by the clerk in the original store and purchases the commodity for sale in the other store, a system is provided so that the original store having introduced the other store can receive a sales commission from the store introduced by the original store. Further, preferably, a system is provided so that the customer can purchase the commodity for sale in the other store at a predetermined discount price. |
