Thank goodness for science. How else would we know the best way to nab those barely-used weed whackers, dumbbells or duck-shape salt shakers on eBay? In a study that gives the lie to the notion that eggheads don't like to eyeball online auctions like normal folks, a study by South Korean physicists confirms via some elaborate mathematical modeling that "sniping" — waiting for the very last second to submit your bid on that Elvis-shape throw rug — is indeed "a rational and effective strategy to win in an eBay auction."

Founded in 1995, eBay is the king of online auction sites. Sellers put up items for sale and buyers bid up the price. Thanks to the Internet's lack of state sales tax and the public's thirst for other people's garage sale items, the company has grown into a firm that amassed $4.55 billion in revenue last year. The service sets a deadline on bids for items, which has given rise to the practice of "sniping," bidding at the last minute to deny other bidders time to outbid you.
