The electronic shelf label displays, for each size, the inventory quantity, together with commercial item detailed information that includes the commercial item name and the price of each commercial item that is placed at a commercial item shelf position to which the electronic shelf label is attached. The configurations also make it possible to display, for each size, the total inventory quantity indicating the number of commercial items that are not placed on the commercial item shelf but exist in the store as inventory.
