Dr. Horrible Finally on iTunes UK and AUS

Finally Dr. Horrible, the video, is available to download in the UK and AUS on iTunes. (The soundtrack has been available for a while.) The cost in the UK is £1.49 per episode, which is about 7 beans and a bucket of cow's milk in the new post capitalist financial regime. Or you can get all three episodes for £3.99, which is two peppers a carrot and a cabbage.

It sounds like it was a bit of pain to get the show onto iTunes in these countries. Why is that then?
