eBay has developed a streamlined method of sniping, due to be introduced next month. Not a program that snipes for you, but a way to monitor the progress of bids in the last few minutes to facilitate your making a bid in response to others. This will eliminate the need to continually refresh the auction page and to have an extra window open for your last-second bid.
