I just got off the isle, and am hunting for tradeskill books (I know. I should have bought the books on the island). Anyway, I can't find any merchant so far that sells them (I'm in Qeynos). I did join my wholesaler tradeskill society in Baubleshire, hoping I could find the books there, but they don't sell anything. I'm pretty sure that I tried every merchant in Baubleshire (though its possible I missed one or two -- I have some eye problems.
Can anyone point me in the right direction? Even if you can tell me what zone you bought yours in (other than the Isle of Refuge, of course -- I'm kicking myself over that now, believe me).
