I make sure to always, always purchase these DVDs. I also try to drop a couple bucks over at iTunes in addition to downloading the HD vids on Xbox Live and voting for The Guild in The Streamys.
And I'm a normal person! Swear!
There's maybe three comedy shows on actual television that are worth their salt at any given time, most of them created by or inspired by a Ricky Gervais production. If I have to drop 15 bucks a year to keep The Office on the air, I'd do it. So I don't see any reason why I shouldn't do it for The Guild.
Every season always turns out to be a thoroughly enjoyable hour-plus of television, in stand-alone episodic format. And with all the extra features, commentary, etc, it's a solid buy with plenty of rewatchability (because yes, that's a word now).
Can't wait for season 4. Who knew Codex was such a big slut?!
