Abstract: PROBLEM TO BE SOLVED: To provide a system for selling travels with donations in which the purchase of the travel with the donation is fully interesting to a customer by relating the features of the travel that many people participate and a similar plan is repeated or the like and donation activities. SOLUTION: When the deadline of the travel passes, the web server of a travel agency judges whether or not the number of applicants is equal to or more than four which is the invited number of people (S31). In the case of four or more (S31: YES), four people are selected from the applicants in the descending order of donation amounts (S35) and the donations of the four people are totaled (S37). In the case that the total money amount is equal to or more than 300,000 yen which is the target amount of the donations (S39: YES), the four people are decided as participants (S41). In the case that the number of the people or the plan can not be increased (S43: NO), the four people become final participants. Thus, the customer wanting to participate in the travel so much pays a lot of the donation. Also, the customer enjoys thrills until the participants for the travel are decided finally.
