Is the one you got exactly like this?
I think that one might be what it really should be like:
Notice the "10 DVD" mark at the top right (just like the picture on yesasia!), among other changes. That finger nub on the back is pretty nice too.
Of course, it might just be another (more convincing) bootleg. I found those pictures on Yahoo Auctions Taiwan after all.
Buying a bootleg is like illegal downloading, except that you lose money out of it... So I personally wouldn't consider it a deal.
