A system and method for delivery confirmation of a short message comprising sending the short message to an recipient communication device, determining that an instant message delivery notification is not received, and indicating delivery failure of the short message to the mobile station. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewer’s chair. In some embodiments, controlling the supply for the discharge generator modifies a property of the discharge to modulate the RF transmission such that the resulting RF transmission is indicative of the device state or other information to be communicated. The inserts include an upper body and a lower body with a rib therebetween. Each retail computing system is also configured to provide a readiness rating value for each planogram, the readiness rating value being based on a comparison of the threshold quantities and in-stock quantities of each product associated with the planogram and being indicative of whether the planogram is ready to be implemented.
