I am selling this as yesterday I got a 72 hour ban and will not be using this key again as I don't want to risk loosing my account.
A lifetime key costs $28 which works out to be between 25-28k gold.
I will sell this Key for the cheapest price of 18k on either Dragonblight or Outland. M
Let me know if you would like this, if I deem you trustworthy, I have no problem with going first.
I will also post proof that I own this when I return from work.
