Crazy though, I was just about to purchase a Gold 'Limited to 500' on eBay for £75 until I saw this thread!
Just purchased the gold through Napalm anyway, it will be awesome no matter how many copies!
But in the description they are saying it's limited to 750 copies. Maybe they changed it to combat the flippers on eBay? Or just a case of supply / demand. Either way, it's pretty naughty to tell people one thing, and then change it after they buy it. Tut, tut....
The real problem, is that I'm probably going to have to buy the silver and the purple box set too!
