An incremental feed device is disposed in the security dispenser, comprising a pusher assembly for advancing merchandise items to the front delivery end, and a stop mechanism allowing the pusher assembly to achieve its travel in a plurality of predetermined increments. When the pusher assembly is engaged with the stop mechanism, an actuator operably connected to the stop mechanism and having an engagable component, must be actuated by a user wishing to dispense a merchandise item, causing the pusher assembly to temporarily disengage the stop mechanism, thereby allowing the pusher assembly to travel in one of the predetermined increments.
