AbeBooks is a terrific site for used books. Plenty of novels published a few years ago are listed under $4 dollars! And these cheap copies are usually ex-library books in pristine condition (be warned, there are more than a few stickers plus tape; apply heat before pealing). It takes about 1.5-2 weeks to receive a book. Occasionally the covers are different than what's shown in the photo but I attribute this problem to individual sellers rather than AbeBooks. It's the seller's responsibility to provide a photo and indicate the edition. If you're ordering books for school, be sure to order early. Obscure works or textbooks may take longer to arrive.
