Assuming the cane up for 110,000 gil is yours, why in the world would you undercut by 40k from the next highest sale price?

I'm gonna yell at you too, right now. Especially considering the fact that there are ONLY TWO total up for sale. You could up your price a little and more than likely still sell it just as quickly.

GM will do nothing about this, since the market is fair game, so you should feel secure about that at least. But man, you're only hurting yourself with such a massive undercut.
