Have you heard of Fatfingers?
I just wanted to share the newest deal hunting tool I found. I learned about fatfingers a few weeks ago and have been playing around with it since then. It is a tool for searching Ebay. You type your search in to Fat Fingers and it looks for any misspellings of your search. So if someone is selling a Kinect but listed it as "Kinnect" no one will be able to find it, which should ensure you a better price.
