A communication terminal executes a position measurement (Sa1) at a prescribed site together with another user's communication terminal, and registers a group (Sa2) by transmitting location information and identification information which identifies a user. A server device specifies a coupon (Sa3) according to a site which the location information denotes, and transmits a segmented coupon (Sa4). Thereafter, the communication terminal carries out, once more with the same user and the same prescribed location, a position measurement (Sa6) and a transmission of location information (Sa7). The server device determines whether a prescribed condition is satisfied (Sa8), such as whether the location information is transmitted with the same members' communication terminals, and if the condition is satisfied, transmits a merged coupon (Sa9).
