Abstract: A system and method (10) for online bidding wherein a seller (16) creates sale terms including a start or maximum sale price (22) and an end or minimum sale price (24) and a length of time (20) for each particular item or service (30) they want to sell. The sale of each item or service (30) items begins at the start price (22) and drops steadily throughout the length of time of the auction (20) until the item or service reaches the end price (24). A purchaser or bidder (12) has full access to the sale terms provided by the seller (16) including the start price (22), the end price (24), and the time length of the sale (20). A bidder (12) can bid based on either price or time.
