I bought 'RAINBOW' and 'I am' at this store in Boston called Tokyo Kid and later found out why it said Alion International instead of avex. I went on
http://www.eneabba.net/ayu and saw that the official 'I am' CD had a white dove while the 'I am' that I bought just had the cover of the CD printed as a CD label. Same thing with 'RAINBOW' but it had a different label.
Also, I bought 'My Story' from 'animefurusato' (the guy who is selling the first Ayu CD bundle) and found out that that one was fake, but instead of saying Alion on the back, it said Miya Records, which is also a bootlegging company. So just make sure that you look out for those.
Now I only buy J-Pop CDs off of yesasia.com and everything they sell is legit ^_^
