Market board logic - how to loose 100k in 8 hours

[RyuDragnier]

Welcome to capitalism.
Besides, that's something I do when people try to sell things cheaper than me.
Undercut me for 1 Gil? I'll undercut you for 10,000 Gil and keep on doing it.

And I'll laugh and keep undercutting by 1 gil until you get to half my current price, buy yours, and resell it at my price to make a profit. You lose, I win.

But to a lot of people, simply clearing it off is a win to them. So hey, everyone's a winner. \o/

Pretty much this.
What people fail to understand is that I sell cheap af for the simple fact I have more of the same thing I'm selling. So unless they buy my whole supplies and then sell it again, they won't be making a profit. Meanwhile, me being an omnigatherer and crafter makes it cheap and easy for me to keep making new stuff to, once again, keep selling.
Unless of course is stuff that my retainers bring to me and I don't want, so I just throw it for dirt cheap.
