Here is a website for new and used books. This none profit company's purpose is to recirculate books so they do not end up in a land fills and any profits the company makes goes to world literacy. There is no shipping costs so the books are really inexpensive compared to bookstores or book sellers. I buy my own book club books here and also find great books for our classroom library. Since there are thousands of inexpensive adult to children books, it is better to know the books you would like to purchase. Then you type it in. Very popular books such as Diary of a Wimpy Kid are available but not the newest books of a series.
