I'm attending AMD Heaven GamExperience in London tomorrow and will have for sale the CS:GO key you receive at the event.
For now I'm just listing one, but I may be able to snag a few more while I'm there, but nothing promised, they could be handed out individually.
Taking offers on the key, and I will have it ready for you to use Sunday morning when I get home (I wont expect payment before then)
leave offers here,
thanks!
