A purchase information input part(110) receives desired goods, anniversary, and purchase joiner information from a buyer terminal(300), and registers the received information to the bulletin board of a buyer. A purchase joining requester(120) requests joiners to join in purchase by informing joiner terminals(400) of the desired goods and the anniversary. A joiner group generator(130) generates a joiner group when the joiner confirms joining in the purchase. A first payment processor(140) respectively receives a part of a price of the desired goods from each joiner terminal.
