www.paperbackswap.com





You can swap paperbacks for just the cost of postage.





www.bestbookbuys.com searches the inventories of a bunch of used and new online booksellers, and organizes them by price, shipping factored in. Includes alibris, abebooks, half.com, etc.





Have you tried used bookstores, thrift stores and libraries?Whats a good book store online that has alot of cheap books for sale?
Check out ebay. The shipping is usually pretty reasonable and if you buy more than one book from the same vendor, they will sometimes combine shipping fees for you.
Even Powells.com and amazon.com have used books on sale even as low as 1 cent. B%26amp;N too
Alibris.com





abebooks.com
If you don't mind ordering used books, I've found http://used.addall.com to be incredibly helpful. You're going to get about the best price you can by searching there...
I know that there or sites online you can join...........it's kind of like an online library...you can go to the site ';order'; books......and you ';pay'; for them by sending in the same amount of books as you ordered....I would do a search for book swap, online library etc...but I put the link for one of them
