Yeah, the whole situation is kind of uncalled for :(. I don't know why it is like that in the US.
I was blindsided by it one day, too. My brother lost my copy, and I thought it was no big deal, I'd just hop online and buy some used one for 10 bucks or so. Only to find the really crappy ones are 50-70, one of which I bought and it smurfed up in 10 seconds and got a refund, and new ones are over 100. Not to mention some without the Greatest Hits on the cover go for over $250+ (check out Yahoo! Shopping for that doozy, although why people go so far out of their way for non-greatest hits stuff is beyond me anyway). I did try looking in actual stores, but no luck there. I live into small of a place for such a thing I think.
The whole thing is kinda odd, so I can see people looking at the PC version these days. Silly Square, don't they know fans need refills every so often?
