I believe Suncoast carries them; failing that, a lot of places should be able to special-order one, or you can buy it on-line. ^_^ It's probably best to go with one of the major on-line vendors that sells the U.S. releases - the real Japanese release is very expensive, and most of the very cheap copies are illegal bootlegs.
Ok That was really random, and off subject read the rules.
I got mine at Sam Goody, but Suncoast and Sam Goody are the same company really, but sometimes I see that Sam Goody has them more in stock than Suncoast so I would go to Sam Goody.
You sure that the .hack//SIGN OST vol. 2 (domestic release) has even been put out w/the acception of the DVD limited release sets? I haven't seen it advertised by one of our vendors yet, and they're the ones that made the deal and got vol. 01's OST out for distribution in the first place.
