An order selection system is disclosed having a downwardly sloped plate, and stationary and movable dispensing means both of which are responsive to a system controller of the system. The system controller has an electronic, device such as a microprocessor preprogrammed with operating routines, which are responsive to a selected order request issued by an external device. The system controller correlates the control of both type dispensers so that each of the products in the selected order request is retrieved from its storage location and placed on the moving gathering belt within a dynamically assigned order space. The operation of both type dispensers is controlled by the system controller so that the controller dynamically assigns space on the moving gathering belt, allowing the controller to service simultaneous order selection requests that may occur from one or more external devices.
