World of Warcraft: Burning Crusade, an expansion pack to World of Warcraft, was released at many Gamestops across the country at 12AM. The expansion pack alone costs $39.99, but if you’re into the game you really want the Collector’s Edition. The limited edition package sells for $69.99, but it comes bundled with a load of stuff for fans like the soundtrack, a behind the scenes DVD and the coveted exclusive Netherwhelp pet. On eBay prices for the collector’s edition have jumped up to double the retail price. Is the Collector’s Edition that rare that it’s sold out everywhere? Just how much is a Netherwhelp worth to a WOW player?
