Undercutting

[dspguy]

You're assuming every seller looks at the marketboard as a game to win.

Not all do. For some, they're just trying to make a bit of gil off things they don't want/need.

That's where it gets weird in a game. Not everyone is participating for the same reasons.

True. Also not like the real world. Capitalism is king and people aren't doing work for free (willingly). Sadly the market gets destroyed by just a handful of players undercutting by 50% because they don't "play the marketboard game" competitively.
