I currently have 2 beta keys for BFA. I have them posted on eBay for cash, but do not trust PayPal users on here.
I will pull them down if someone gives me a good enough offer.
I will sell them for wowtokens (darkspear us server)
Or
Services like mythic antorus run or such.
Or
If you would like to trade for cash, I believe there are middle men on this site I do not mind using but you will pay fees for it.
Feel free to add me on skype (live:d.wozny_5) or discord WorkingCorgi#4831 to discuss any trades.
