We have very strict refund and return policies, so please make yourself aware of them before you purchase from this website.

No refunds are available for digital media.

There are no exceptions to this policy. Digital media is too easily copied and retained. It cannot be returned or refunded.

Should you wish to return one of our printed books, we will accept it as long as it is received within 14 days of your receipt, as indicated by the dates on postal delivery records.

Upon inspection of the returned book(s), we will reimburse you the amount you paid for the book, minus the cost of shipping (as indicated by postal records), and minus an additional $15 handling, restocking, and payment fee (which we are required to pay to our payment processor, even if we refund your money).

If you decide to return your book(s):

Send us an email describing your plans along with a copy of your receipt. We will provide you with the address to send your book(s) to, and will give you the refund amount to expect. All refunds will be applied to the credit card you used to pay for your book(s).
