Abstract: Embodiments of a Retail Merchandising Unit (RMU) comprise at least one door for securing items within the RMU. The door(s) comprises a transparent portion that provides security for the items contained in the RMU, while allowing at least a portion of such items to be viewed. Preferably, the transparent portion restricts access to the RMU's interior, while permitting at least a portion of the items that are secured within the RMU to be viewed through such transparent portion. The door(s) may further contain one or more shelves on which merchandise may be placed, wherein the shelves are arranged such that when the door(s) are closed the shelves are secured within the interior of the RMU. Preferably, the transparent portion of a door permits the items placed on the door's shelve(s) to be viewed by passersby. Embodiments of the RMU may provide a self-contained storefront for marketing and selling merchandise.
