And I can say for a fact that being exalted with UC doesnt make any difference..

You need to complete a quest to make her able to sell the stuff to you. Is the quest where you get sent alot of letters telling you to speak to someone relatives. Does nothing but make them able to sell you food and water. Pretty useless IMO, and Blizzard forgot to notice you that you can't actually speak to them as in the letter described. Only be able to buy some crap form them.

I talked to her and she had nothing to sell, It was probably like, eventful for her to sell that stuff but Blizzard just forgot to remove her after it was done. =|

I'm alliance and I got this. Might try and stealth to it :D
