It's simple...they collect used books and resell them. But on top of that they also donate a book to someone in need. They take cast offs from libraries, surplus stock from bookstores, and will even take your used textbooks!
If you're in the States and are lucky enough to have one of their handy drop off bins in your community, donating is easy!
Or maybe you just want to buy a book...
The have loads of categories of books and you can filter selections by price (from under $5 to over $20), condition, format, intended reader age, etc. And lots of books have FREE WORLDWIDE SHIPPING!
What are you waiting for? Donate or buy and make difference in someone else's life.
