eBay sells a world of products, including BlizzCon memorabilia. For those true fans who couldn't make it to BlizzCon, it's their dreams come true.
It is possible to have too much of a good thing, and some Blizzard fans are shelling out hundreds of US dollars in order to get their hands on BlizzCon souvenirs. On eBay, you can now buy Murlocs, access codes to a future beta from Blizzard, and even completely intact BlizzCon gift packages. The highest bid right now is $400 USD (asking price is $600) for a baby Murloc. Some other items of interest include:
-Exclusive BlizzCon posters - $150
-Limited edition laser prints from World of Warcraft - $100-$300 (one has been autographed by the Blizzard development team)
-Murlocs/BetaKeys - $100-$600
-Autographed Starcraft: Ghost posters - $50-$75
