you dont have to buy it. they should call you and let you know when it is in, but you can always say no when you look at it.
my friend works at hmv, and ive just asked him about it.
so just order it, and let us know what its like!
i ordered ultra blue, heart station and singles collection volume 1 from hmv, and all were canadian versions that are JUST like the japanese versions. ultra blue even had the first press picture on the disc label.
