Abstract: PROBLEM TO BE SOLVED: To acquire, in accordance with a user picking up a commodity before purchase, a behavior of the user regarding the purchase of the commodity thereafter and grant a coupon to the user with prescribed timing, thereby enabling a real store and an on-line shop to coexist. 
     SOLUTION: A purchase probability calculation unit 107 calculates, upon detecting that an event regarding purchase of a prescribed commodity has been carried out, a purchase probability of the commodity, irrespective of whether being a real store or an on-line shop, in accordance with a type of the event, and increments or decrements the purchase probability of the commodity in accordance with each event. The purchase probability calculation unit 107 reduces the purchase probability by a numeric value obtained by multiplying a prescribed coefficient to elapsed time. An assessment unit 108, when having assessed that the purchase probability has exceeded a purchase threshold, outputs the assessment result to an information delivery unit 109 and when the purchase probability falls below a prescribed lower-limit value, outputs the assessment result to a control unit 101.
