These are timed deadline auction sales. The seller sets the end time for the auction and the buyer has the option of bidding against other bidders. A reserve price may be set to ensure that an item does not sell for less than a set value and the seller may offer a fixed BUY NOW price as an option.
These are auctions which are due to start sometime in the future. The seller may alter the terms of the auction before it starts, therefore buyers can add them to their favourites to watch the auctions.
These are items for sale at a fixed price. Buyers can view items and if satisfied with the asking price, simply click and BUY NOW.
