Abstract: A method of distributing goods obtained from a seller through use of auction services. A store obtains goods from a seller and the goods are specifically identified and clear title to the goods is verified through a database via law enforcement agencies. The database is used to automate listing such goods in online auctions and monitoring the auctions until they conclude. if the auction concludes with a buyer, the goods are shipped and the buyer has a finite amount of time to inspect the goods and either accept them or reject them. if the buyer accepts the goods, the buyer's account is debited and the proceeds are distributed to all appropriate parties.
