I just found an Adult Swim sale at JB Hifi's online store.
All seasons are $15.98.
Includes Metalocalypse, Sealab 2021, Aqua Teen Hunger Force, Robot Chicken, Harvey Birdman, The Brak Show, The Venture Bros, & Frisky Dingo.
These are the best prices I've seen.
Postage is $2.80 for 1 disc, $4.20 for 2. The postage examples don't go beyond that.
sweet. been waiting for this to happen again.
