I'm gonna turn this around and tell about the best bazaar deal someone else got....
Once upon a time, there was a young newbie wizard named Wargren on the (then) Xev server. I happened to be walking past the main bank in PoK while someone was clearing out his toons (he was leaving EQ). I asked if he had any INT items. The person responded in the affirmative and handed me a head piece that had +5 INT. However, I discovered a few minutes later that it was for mages only. I figured 'What the hell, I can't use it but maybe I can get a few plat for it' and put it on my trader for 1k. Imagine my surprise and joy when I saw that it sold in about 3 minutes. 'Who would want that lousy piece of crap for 1k?' I asked myself as I laughed my way to the bank.
The head piece? Crown of Elemental Mastery (for the mage epic), which, at the time, was going for somewhere in the neighborhood of 100-125k. I still cry myself to sleep at night sometimes because of that. And, if you happen to be the one who bought it from me...you're welcome. /weep
