I would imagine that, since this thread is still actively being bumped and has yet to be locked or updated to indicate otherwise, I would say it is safe to assume that they are still being sold.

As a quick tidbit, I have received my audio-book as hilarious has been extremely accommodating. I was unable to utilize the code in it's original form, so they helped me out with the download format and even my specific interest. If you're considering grabbing this, I would just say go for it. They are extremely trustworthy and once you have your file downloaded, nobody can take it away from you.
