A rectangular shaped lockable bin is defined by four walls and a bottom wall. A lid is hingedly mounted to the rear wall and has a slot located in a front portion thereof. A lock having a latch is pivotably mounted to the front wall of said bin at a pivot point and is configured to be selectively rotated between a locked position and an unlocked position by an actuator. A tail extending from the lock contacts a post located on the wall of the bin and basis the lock in the unlocked position. A series of such bins may be received in a delivery module, which may be received in a drawer.
