The auction watch feature notifies you of newly listed auctions. After logging in, go to your desired auction, and click the "Watch This Item" link.
The item watch
features lets you keep a close eye on any auction without having to
place a bid on it. This feature means you can be kept up to date on how
an auction is doing and prepares you to place a winning last minute bid.
Each time a user has placed their bid, you will be notified via email.
