Cash4books.net is a great website that allows you to sell your gently used books (and audio books). You don't even have to pay for shipping. That's right, the shipping is FREE! Just print out a barcode and take it in to the mail center of your choice. They will scan the barcode, printing out the already paid for shipping sticker!
I've used this site, and it's great! They even will accept my old textbooks.
Cash4books.net is really easy to use. Go to their website and see how much extra money you can get. (You don't even have to sign up for this feature.) All you have to do is put in the ISBN number and they will tell you weather or not they will take your book and how much they will pay you.
You even have the option of getting paid with PayPal or with a check, and their processing is really fast!
So, what do you have to lose? Try them out today!
