Partnership: Cash4Books and DonorsChoose.org

I love the site Cash4Books.  I have done a lot of business with them and it is always a smooth transaction.  Cash4Books allows you to sell all different types of books, fiction, non-fiction, textbooks, etc.  They have teamed up with DonorsChose.org which allows you to donate books by making a donation.  The only requirement is that you must be sending in at least $7.00 worth of books.  When it comes time for you to sell books, you can choose to donate $5 or $10 of your book sale payment.  Cash4Books even donates 10% of your donation to reading and literacy programs. 

When you have chosen what books to sell, you can receive payment in the form of a check or via PayPal.   Another great thing about this service is that you can recycle your books which is good for everyone.  Plus, you don't have to pay for any of the shipping costs for any books that you sell to this company.  If you are selling 5 or more books, you can send them via FedEx which means that you will receive your money sooner.  If you have less than 5 books, you can send it for free through the post office.
