YES!  Whenever an ePub version of a book is available (which is most of the time), we can send the book directly to your kindle device or kindle reading application.  It does require a bit of setup on your end (in terms of adding our kindle email to your Amazon trusted list allowing it to send to your device, and providing us with your @kindle email address) but you can do all of that quickly and easily via your Settings.

You can find more detailed instructions on setting it up in the ePub section of this FAQ question.
