Thought I'd take a shot (no pun intended) at tossing a few of those onto the AH as a possible money maker - nope - not sure if the guy posting them is doing it on purpose or he screwed up but one guy has four pages of the suckers going for a whopping 2g a stack (way less then the AH value of the mats on my server and since they're 450 skill its not like he was skilling off of them).
Got happy at the thought of simply flipping them to a merchant but they've got the whopping sell price of 3 copper a stack - ah well, at least they'll be cheap skill ups for Cat.
