This can be used by sellers to sell their items to many potential buyers.
Auction in which one seller offers item(s) for bidding and several buyers compete to offer the price the seller will accept. The seller usually has the option to accept any bid or reject all. Types of forward auction are (1) English auction: Bidding starts at the minimum price acceptable to the seller and increases with every new bid by a fixed increment. Every bidder knows what price is being bid and the highest price bid acceptable to the seller wins. (2) Dutch auction: Bidding starts at a price so high no buyer will accept, and which is lowered until the best acceptable price is reached. Used typically for perishable items like flowers and vegetables.
