Abstract: Systems, methods and computer program products are provided for anonymously buying and selling regulated goods, such as agricultural chemicals, via auctions conducted over a computer network. A seller of regulated goods submits a request to the Web site of an intermediary to list the regulated goods for sale. The intermediary verifies that the seller is authorized to sell the regulated goods using information about the seller maintained by the intermediary. The intermediary also verifies that a bidder is authorized to purchase the regulated goods using information about the bidder maintained by the intermediary. The intermediary initiates delivery of the regulated goods from the seller to winning bidder(s) and initiates a transfer of funds from winning bidder(s) to a seller.
