Looks like they are really discounting down a ton of their bargains, including whole series boxsets and thinpacks (most of them down to $15 - $20 a boxset) and many individuals for mere bucks. Sale to end May 3, 2010, so you'll probably want to get in quick.
I picked up the first 8 volumes of Gatchaman
Collector's Edition at $2.69 a disc. Pretty crazy price to get a classic series.
