What's your definition of "low price" Adiman? Might have more luck if you specify a figure you're willing to go to.
I did mention in another thread that I got my copy off eBay for Ãƒâ€šÃ‚Â£8.50 + P&P. To be honest, I think you'll be hard-pressed to find it cheaper than that. GC games now have greater longevity with the ability to play them on the Wii, so they are holding their value quite well.
