A vending machine has an outer housing with a hollow interior and a manual retrieval opening. At least one tray is removably supported by the housing inside the interior thereof. The tray has a plurality of storage bins, each bin being dimensioned for receiving a plurality of items to be dispensed. Each bin has a movably actuable mechanism for ejecting a single unit of the item therefrom. A manually operable coin mechanism is mounted to an exterior of the housing for receiving a predetermined number and size of coins. Insertion of the proper coins into the coin mechanism permits a single actuation thereof through a predefined range of motion. A manually operable selector mechanism is mounted to the exterior of the housing for designating the item to be dispensed when moved into engagement with the ejecting mechanism of a preselected one of the plurality of storage bins. A drive mechanism is coupled between the coin mechanism and the selector mechanism for enabling the predefined range of motion imparted by a single actuation of the coin mechanism to actuate the ejecting means of the preselected one of the storage bins. This causes a single unit of the item stored therein to be dispensed to the manual retrieval opening of the housing.
