I see seasons 1-2 of Alex Mack on itunes USA.
Priced from 12-15 dollars.
So far though, no Australia offer!
I'm really miffed at Australian iTunes, because everytime I look at the us site and compare it to the Australian site, the shows I want aren't there!
It took us ages to get Danny Phantom season 3 and My Life as a Teenage Robot season 1.
And still waiting for the rest of the Teenage Robot episodes.....
