A system and a method for delivering information related to the evaluation values of products. The system includes an evaluation database (DB) for storing evaluation information; a user terminal for reading the product codes of products; and an inventory information DB for storing inventory information. The evaluation information is read, based on a product barcode obtained by the user terminal, from the evaluation DB, and a retail store within a predetermined distance from the user is searched based of the positional information (GPS) of the user terminal. Then, the inventory information DB, which is connected to the POS server of the retail store, is searched to acquire and display the inventory status of the product on the user terminal. Additionally, when the product is purchased, the evaluator who provided the evaluation information of the product is given points and paid a reward.
