I was used to my free Xbox Avatar items with pre-orders (Halo Combat Evolved - Master Chief Armor; Mass Effect 3 - Normandy prop). What about the Witcher? I noticed in their main portal that the avatar item is offered, but I can´t see it here.
Amazon orders get the digital comic book as a pre-order bonus. Gamestop has the keychain, and Best Buy has the t-shirt. The avatars may be bonuses for overseas orders, as stated from The Witcher's website: "The following additional content available for Enhanced Edition varies by vendor and country."
