From messing around with the bots on my server, they can set a price floor specifically so people can't bait them into selling at a huge markdown then buying them out.

You can still abuse this by figuring out what price they won't go under then selling just below that so you don't have to worry about them undercutting you until they bother checking the prices manually.

However, they're liable to just keep adjusting the floor to be lower and lower each time in hopes of scaring off the competition, after which they'll try to jack up the prices again.
