I have been and will be actively buying Kwuarms and Irit Leafs for the next few weeks. Currently offering:

Kwuarm - 4k each
Irit Leaf - 3k each

I have these offers in the sell tab of the AH so you can sell directly to me without having to trade me in-game. I might consider buying other herbs but I'm primarily looking for Kwuarms and Irits. Please reply if interested! Anything helps!
