Monsoon website for selling second-hand books, is set up to match Amazon's lowest price. Occasionally, to steal a bargain, people will put up fake listings of an expensive book they want to buy, but with ridiculously cheap price. Then wait for price-matching algorthm to kick in to drop price of their targeted book.
