Well that is interesting about the tax and if you didn't catch it, I was joking about owing SE money. Relative to motivations for selling at one gil, one can do it if they so choose. If it's to clear your inventory and give it to someone, fine, the more power too you. On the other hand it does at least temporality upset the standard pricing for an item that some work at to sell.
I use the market board/retainer system a lot. It's just part of what I do everyday. For the most part I think it works pretty well.
