Hi,
I got extra keys, looking for €9 via PayPal/Skrill/Paxum.
Please PM me your skype or e-mail and I will add you/send you payment information. After I have received the money, you get the key.
Additional information:
There won't be a wipe in Hearhtstone, all your progress will carry on after beta.
With a fresh hearthstone account you also get a free arena pass and a booster pack.
2 keys left - €9 per key
