Abstract: If a customer has picked up a product from a display shelf, a display device displays first sales promotion information. In an information providing system, if the customer has not been attracted to the product and has returned the product to the display shelf, the display device displays second sales promotion information, which is different from the first sales promotion information. By displaying the different pieces of sales promotion information using the display device provided near the product, it is possible to promote the product to the customer in two different ways, thereby stimulating the customer's desire to buy the product and reducing loss in opportunities to sell the product.
