As of now, the DVD is only available for sale in the US on Amazon and through the Foundation website (although it can be shipped from there to other countries). We are currently working on getting it on Amazon in the UK and Canada. In addition, we are working on the process to make it available (via Amazon Video Direct) as a digital download in the United States, United Kingdom, Germany, Austria, and Japan.
We will post any updates on this as we have them, hopefully within the next couple of weeks.
Thanks for your patience
