I just heard from Arvind Ethan David (the Executive Producer of DIRK GENTLY) that the episodes will be available to purchase on the USA iTunes store the day after the episodes air on BBC America. It’s not up on iTunes yet but hopefully the price of a ‘season pass’ is reasonable enough so that those of you whose cable or satellite provider doesn’t have BBCA, can watch it via iTunes. And yes, I know there’s *cough*torrents*cough* but we don’t talk about that. FightClubRules ;)
EDIT: The episodes will also be available to purchase on AMAZON.
