I just want to throw in another online store in California.
www.tmpanime.com
Tam sells only licensed legitimate product and prices are pretty good since he has no overhead expenses, and based on about 5 purchases already, you can message him quick if htere is a problem and he will adress it just as quick and delivery times are incredibly fast, within a few days or purchase. I picked up 4 volumes+ artbox of Angelic layer from him for about $95 including shipping, and many titles hes got are about $18-20 each. Hes a very friendly person and is glad to special order anything that he doesnt carry yet, as hes done this for me several times. there is a forum there much like htis one, and its just an incredibly great place to sign up at and buy from. highly recommended.
