Our bookstore sells books only in epub format, which is the industry standard.

In addition, the text of the confirmation page, which is displayed before a purchase is completed, specifically mentions:
Unfortunately, at this time, Amazon does not to support this format, and uses instead their own proprietary format. Kindle is not compatible with epub format.

Kindle Fire users
The Kindle Fire does not natively support epub format either, however since it is an Android tablet, all you need to do is install the proper reading app to read any books from Feedbooks. We recommend Mantano Reader or Aldiko, both available free from the Android Market. Please take a look at our help page for Android devices for more details:
