PROBLEM TO BE SOLVED: To give points corresponding to a buying price to the buyer who buys a commodity through electronic commerce and to give pints to a person who introduces the buyer at a fixed rate to the points given to the buyer. SOLUTION: In the electronic commerce through which an application for a purchase of a commodity is sent from a buyer terminal to a shopping site though a communication network, service points SP as a discount amount for a next commodity purchase are given when a purchase of a commodity is reserved (step S11), persons who introduced this buyer are hierarchically traced back and retrieved (steps S15, S17), and bonus pints obtained by dividing the service points SP at a variable ratio are given to each of the introducing persons (steps S19, S21, S23). |
