ABSTRACT:
An authenticated user is provided with page information relating to a service to be provided, such as a service for ordering products. In the invention, the authenticated user is provided with page information in either a first or second form, wherein in the first form the page information includes an entry field for coupon information and in the second form the page information does not include the entry field for the coupon information. When coupon information input in the entry field is received, a determination is made whether or not the coupon information is valid. The number of times that the coupon information is determined to be invalid is counted and stored in association with the authenticated user. When the counted number does not exceed a predetermined value, the user is provided with the page information in the first form, while the page information is provided in the second form when the counted number exceeds the predetermined value.
