• We do not collect any information about you other than what you type into the fields, such as your email address and your comments--if you have joined one of our newsletter lists, you did so voluntarily and can be unlisted at any time.
• We keep a record of purchases and shipping addresses to ensure that packages are sent to the right address with the right products.
• That is it.  We have no intention, interest, or time to invade anyone's privacy, and we do not sell, rent, or loan information to anyone for any reason whatsoever.

We do not accept returns on books because what is being sold and purchased is intellectual property, which is delivered in the form of a book.  Once the book has arrived, the information has arrived and therefore the customer has received in full the property therein.

Furthermore, since the books sold on this website are textbooks used in college courses, they are not returnable. 

If you want to buy from a company that allows returns, please buy our books from Amazon.com.
