I'm wanting to buy a Hearthstone key for 20 bucks via paypal [or some very easy way to use a card]. Scammers do not bother, I am only willing for YOU to go first. I will report (and post) about people who seem untrustworthy or try to scam me. And I am not willing to do the whole 50% now, 50% afterwards method. That is prone to scammers. I am a long term member of this forum, which means I am much more trustworthy than other random people.
Also, yes I know the price is often much higher than this. I don't care. A beta key is not worth more than 20 bucks to me.
