1. A system for use by a supermarket, the system comprising:

  • a first display case including a first controlled environmental space that is adapted to maintain products, the first controlled environmental space having a first varying and measurable parameter, and a first sensor coupled to the first environmental space, the first sensor sensing the first parameter and generating a first signal including a first parameter level;

    a second display case including a second controlled environmental space that is adapted to maintain products, the second controlled environmental space having a second varying and measurable parameter, and a second sensor coupled to the second environmental space, the second sensor sensing the second parameter and generating a second signal including a second parameter level;

    a processor and memory in communication with the first and second display cases, the memory including a first predetermined parameter value associated with the first sensor, a second predetermined parameter value associated with the second sensor, a first set of message strings associated with the first predetermined parameter value, a second set of message strings associated with the second predetermined parameter value, and software instructions executable by the processor to configure the processor to receive the first and second signals, receive the first and second predetermined parameter values, compare the first parameter level with the first predetermined parameter value, responsive to a relationship between the first parameter level and the first predetermined parameter value, retrieve at least a first message string from the first set of message strings, encode a message including the first message string.
