Fast, Easy, $$$
Wow! I found out about CKY Books by Googling "best places to sell your books" and they were not kidding! CKY was EASY, FAST, and they actually paid me $120 for my old books that were just collecting dust. I also did not have to pay to ship the books. They didn't seem to buy children's books (most they wouldn't buy or offering almost nothing) but they bought novels, textbooks, etc. I would definitely recommend CKY to anyone.
