I just saw this web site that helps you get brand name products cheap on Ebay.
It's called AuctionIntelligence, and it's a great idea.
You type in the keywords you are looking for, such as 'Playstation' and it searches Ebay on all the auctions with the misspelt versions of the keywords. If he keyword is wrong (i.e. palystation) then nobody can find the auction, ergo fewer bids and lower prices. I tried it, it works.
It's a very clever idea and a must for cheap bas..rds.
I wonder what other such ideas are there that test the limits of search technologies.
