A method and system for auctioning or sales of deliverable prepared food via the Internet permit customers to purchase or bid on prepared food items. A food preparation and delivery portion of the system includes a delivery vehicle, which may have a mobile kitchen for the preparation of food items en-route. The location of the delivery vehicle is determined from a global positioning system (GPS) receiver in the vehicle or via another location-finding mechanism. Food items with an estimated time of arrival (ETA) is displayed on a web page that provides an interface for purchase or bidding. Bidding may be made for the actual food item purchase or for a scheduled delivery time. Items may be re-auctioned, causing the delivery of a food item to be transferred to another bidder. Audio and/or visual communication with an ordering point and/or delivery vehicle may be provided in the user interface.
