<p>When a first product is placed in a digital cart, an acquisition unit (101) acquires a second product which is similar to the first product, a first reward which is provided on condition of an order of the first product, and a second reward which is provided on condition of an order of the second product. A presentation unit (102) presents a form which has positioned therein a first object associated with the first product placed in the digital cart, and, if the acquired second reward is more valuable than the acquired first reward, additionally has positioned therein a second object associated with the acquired second reward. If the first object is manipulated, an acceptance unit (103) accepts the order of the first product. If the second object is manipulated, a cart management unit (104) places the second product in the digital cart.</p> |
