This invention is a vending machine and components parts that include a sophisticated product retrieval and delivery system. Following product selection, the positioning system quickly transports a retrieval device to the front of a tray queue where a product container is retrieved. The positioning system transports the gripper carrying the product container to a delivery port. The product is released and slides down a specially designed chute into a specially designed delivery bucket that is then tilted outward for customer pick up. Sensors associated with the bucket detect the delivery and removal of the product container. Related methods are also disclosed.
