For people living somewhere near the Quad Cities this site is a bargain.   My link is to the tools auction/classifieds but there are a lot more categories.  I guess now that I'm thinking about it I'll post the main page link too.

http://qconlineauction.com/  Main page with all the categories.  I check it each day and have made the trip to the area for some bargains.  Tools a lot of times for a fraction of the price, people who've inherited something and just want to get rid of it or people with lack of garage space.

It costs nothing to register and most of the stuff is actually a classified but there are some that put it on as an auction.
