I promised one of the programmers here a plug for his hobby site he does at home for fun.
It helps you find the cheapest place to find your books:
http://www.bargainbooksearch.com
Check it out and maybe give him some feedback. There is a link on his site I think that emails him.
I tried it out and it found a book for me that I paid $27 for at Barnes & Noble store at our local mall a few weeks ago for only $16.50 from Walmart.com. I was shocked to find out that Amazon which I thought was pretty darn cheap woulda cost about $20. I believe he includes eBay prices for the book in his results too when he can find it on eBay.
