Abstract
Abstract A shopping cart attachment includes an advertisement and a calculator including a display. The calculator displays a message related to the advertisment on the display, in response to a predetermined occurrence such as depression of the CLEAR key. Because the calculator displays the advertising message, it is difficult for the shopper to ignore the advertisement. A freestanding pocket or desktop calculator may also display a message related to an advertisement on its case or housing, in response to a predetermined occurrence.
