i disagree with the npc them, charge more for them, who cares i would gladly pay as much as 20k for these. because it's the best way to get money back on alchemy skillups and goldsmithing
don't npc them just price them up to match the npc or profit you a little bit more because people skill up off of these... some people are just ja/s' like that
What people don't seem to realize is that the market sets the price, not the players. It doesn't matter if you raise the price if no one will buy at that price.
