Idea against Undercutting at the Marketboard (The next.. )

[Sibyll]

Listing fees prevent relisting but it doesn't prevent the above from happening, the initial undercut.

If someone is able to do this then that means the other sellers in the market were listing well over the value of the item. If this product moves quickly then one person selling a few items at minimal profit could either be bought and resold at a higher value by the competition or will be bought immediately and the higher products will be purchased as well.

I'm not saying it's the best approach, but your argument is that it's a bad option because it doesn't prevent an unavoidable consequence of market boards as a mechanic. Kind of a loaded argument.
