If you got in on the $25 GCU via the deal in the above thread, check your email. There should be an email from them titled 'Call of Duty Race to Prestige | Gamers Club Unlocked Membership'. Inside you'll find a promo code and instructions to get an additional 2 years of GCU for free. This will stack with the 2 you originally purchased, netting you 4 years total.
