For a scheduled purchase, a point count setter sets an upper point usage limit in accordance with an operation. Based on point management information, a discount payment controller controls payment for the scheduled purchase so that the payment is executed at a discount based on the upper point usage limit set. A limited-time point count notifier determines the number of limited-time points scheduled to be used based on the point management information and the upper point usage limit, and before the scheduled purchase is executed, notifies a user of the number of limited-time points scheduled to be used. For a scheduled purchase in a series purchase, a revision suggestion notifier obtains the number of the user's points, and based on how the difference between the obtained number and the upper point usage limit occurs, gives the user a notice to suggest revising the upper point usage limit.
