Examples provide a height adjustable tray including a service surface for moving one or more items from a first height near the top of a display case down to a lower height within reach of a user in a seated position or otherwise unable to reach a top surface of the display case. The tray is connected to a set of one or more support arms. A gearing mechanism moves the set of support arms along a range of motion to lower the tray from the first height near the top of the display case to a position in front of the display case at a second height. The tray remains in a horizontal orientation substantially parallel to the floor or ground surface as the tray moves through the range of motion. An operating mechanism controls movement of the tray along the range of motion.

Systems and methods for a modular store system are disclosed. In particular embodiments, each modular store system includes one or more pre-fabricated, metal, interconnected, modular, units. Each of the units includes a baseplate, one or more chassis (possibly with one or more utility access holes), and subdeck. Each unit may also include other components, such as casters, level glides, a detachable veneer, pre-installed utilities, kick-plates, etc. As will be understood from discussions herein, pre-fabricated, metal (modular) units may reduce or eliminate the timeframe and associated costs of typical on-site (wooden) casework construction.

A sales registration apparatus includes a scanner to read information from a commodity, a main body section to be disposed on an upper surface of a checkout counter and housing the scanner, a display mount attached to an upper end of the main body section; and an arm section attached to a side surface of the main body section and including a shelf surface extending in a plane parallel to the upper surface of the checkout counter. In some examples a peripheral device can be disposed on the shelf surface. In certain examples, the scanner is a bar code scanner.
