A system for controlled advancement of product. Systems of this invention includes a pushing system having a track, a pusher, and an optional resistance mechanism. The resistance mechanism couples to the track and the pusher, controlling forward movement of the pusher along the track and thereby controlling the speed at which product is advanced for access by the consumer. Certain embodiments of the invention include additional mechanisms to further limit the forward progression of the pusher along the track, such as a stop mechanism or an indexing mechanism.
