selling portals for an hour in Dalaran. It's good to be a mage!
edit: To all of you claiming I'm a total jerk for this, boohoo. I am spending my time and, on a lesser note my reagents, I have a full right to be compensated.
Along with that, I don't charge anything. I just say that tips are encouraged. And most people tip me 5g or so. Thanks for judging!
