For preorders, your credit card will be charged on release day.
Because of this, they must be purchased individually, and in a separate transaction aside from any other books.
Adding a preorder book to your cart will cause the cart to be emptied if it contains other items (sorry!).
If the release date changes, you will receive an email notification.
For preorders, on book release day, check your email for a new message from [email protected], which will contain a link to get your book and will guide you through getting your files onto your computer or device. Help is available at every step. The good folks at Bookfunnel offer customer service that can walk you through any quirks unique to your device or software.
