I do, but they're not even released here (lol Belgium) and are ridiculously overpriced (4 episodes per volume, 35€ ~= $55 per volume).
Like I'm going to pay 250€ for Ergo Proxy when a regular season from a TV series costs between 30 and 45.>>10561497
$25 would already be nice.
Best price tag for me would be 60 € for 26 episodes. Not too low, but affordable.
