Not every eBay seller throughly spellchecks their listings, a little fact you can exploit to buy stuff for cheaper, says Kiplinger's:

4. Search dumb. Try misspelling the search term. While everyone else bids on the Duncan Phyfe table, you could have the "Duncan Fife" table — same antique, wrong spelling — all to yourself.

Fewer people finding the listing means fewer people you have to bid against, which means you can end up with a lower closing price. — BEN POPKEN
