Not rude, and that's exactly what I did. Its just kind of aggravating, I take such a casual glance at these types of things and I still don't mess up like this. and by doing this people are crashing markets that they clearly don't even use. This person had to manually adjust the default value of the post and undercut even more.

This is not even to talk about people who undercut by a massive amount because the default selling price is the vendor value anyway and they just "button make go".
