Penalize players who adjust their prices too frequently

[Mavlok]

Undercutters suck in 2.0, pure and simple.

How many times have you seen X put up an item for 150k gil, only to get undercut by Y who lists the same item for 140k gil? Now X comes back maybe an hour later, sees he was undercut, and adjusts the list price of his item accordingly, say to 135k. Y happens to be sitting at the market boards when this happens, and decides to drop his price once again as well, to 130k. After 2 or 3 days, the selling price of the item is now half of what it originally was.

That's how free markets work, yo.
