Various embodiments of the wheel positioning assembly are adapted for facilitating the insertion of a cart into an enclosure. In certain embodiments, the cart comprises: (1) first and second fixed front wheels that are disposed adjacent opposite front lateral sides of the cart; and (2) first and second swiveled rear wheels disposed adjacent opposite lateral side of the cart. In various embodiments, the wheel positioning assembly comprises: (1) a first wheel guide for physically guiding the first, fixed front wheel into a desired first-front-wheel position in which the first front wheel is disposed within the dispenser and adjacent a first wheel barrier; and (2) a locking mechanism for selectively maintaining the second rear wheel in a desired second-rear-wheel position within the dispenser. The first wheel barrier and the locking mechanism may selectively cooperate to physically prevent removal of the cart from the enclosure.
