I received a request from betterworldbooks org to determine if an order I'd placed in June had arrived. Yes! As usual, the order was received in a timely manner.
Tip for consumers: The site speaks for itself. It's easy to use. You don't have to register to purchase their books, but for me it was easier and more convenient.
Products used: betterworldbooks org is a site I often use to purchase used books in good condition. The organization ships for free and also donate books to nationally as well as around the world. Some of the used books I purchased were sent from other countries. It's a great place for avid book readers to purchase books in good and mint condition at reasonable a reasonable price. Plus, by purchasing books through them it allows them to donate books around the world and into other countries to people who may not be able to afford books.
