A drawer for use in a dispensing cabinet is comprised of a tray movable between an open position and a closed position. An insert, approximately the length of the tray, is carried by the tray and defines the volume of the drawer. A lockable or sealable lid is carried by the insert. A release mechanism is provided to connect the insert to the tray in a manner that allows the insert to be easily disconnected from the tray. Removal of the insert enables inserts to be swapped so that inserts from which inventory has been depleted can be replaced with stocked inserts. A dispensing cabinet and a method of restocking the cabinet are also disclosed.
