, misspelled auction searches have quickly become lucrative for people searching for deals. The concept on which these searches are based is that, if an individual posts an auction and misspells its description and/or title, regular searches will not find this auction. However, a search that includes misspelled alterations of the original search term in such a way as to create misspellings, transpositions, omissions, double strikes, and wrong key errors would find most misspelled auctions. The resulting effect is that there are far fewer bids than there would be under normal circumstances, allowing the searcher to obtain the item for less. A series of third-party websites have sprung up allowing people to find these items.
