The auxiliary display (24) includes a display (54 or 56) and an electrical connector (52) coupled to the display which couples to another electrical connector (50) on the electronic price label (18). The auxiliary display is suitable for displaying promotional messages, which may include price information. Circuitry (48) within the electronic price label senses connection of the auxiliary display to the electronic price label. The circuitry sets a configuration bit within a memory (47) of the electronic price label.
