I feel like there should be a limit on how often an item's price can be changed.

The undercut bots can set a price floor they won't go under. In his case, it seems to be 150K on most of the 5.05 crafts.

It's really only exploitable for profit if the bot in question is not relisting items very often, but he's doing it every five minutes or so.

So undercut their 150k floor.
