lol honestly, if you want an opinion from someone who's bought mainland releases -- it's only "fun" to buy mainland releases when you're actually in the mainland. a) b/c its so freaking cheap, b) you get a free poster depending on where you go (i got four this time

). really, if you're purchasing online, shipping costs are gonna make it not worth buying. i would stick w/ taiwan,hk, or japan versions if buying online.
btw -- once you get past all the logos/stickers on the cover & cd itself, there is NOOO difference b/w them and other versions (well, except translations sheets and whatnot). just reiterating
