Well, you can always hope that someone trades in a copy of FF VII at EB Games, although the chances of that are quite slim... This may be a long shot, but have you asked the staff at EB if it is possible to get a copy ordered in (don't know if you'll have much sucess with that though, considering how long ago the game went platnum here.).

Besides that, sure have a look at ebay. Though make sure that you get the PAL version...I have been dumbfounded at how many people get the NTSC version and then say, "why the heck can't I play this game??".

Sorry I couldn't be of much help. Good luck and happy hunting.
