Any spare BF3 keys from the Humble Bundle?

Does anyone have any spare BF3 keys from the recent Humble Bundle they would be willing to pass my way? I've already given the ones I had to friends but I'm looking to get 2 more keys to get another few mates interested in the game. If you have a spare key and would be willing to part with it, please let me know in this thread or by PM and what you would want for it.

Many thanks
