Undercutting.

[Barboron]

You do realize there is a "sale history" tab when you put something up for sale that shows you how much, and when (date and time) items sell for, right?

Yeah but it doesn't tell you how long it is up there for for every single item. I gave you reasons as to why I may undercut myself. That doesn't mean I do it every chance I get. Since you brought up the sale history tab, that doesn't quite put this situation into perspective. What if another player came and undercut this player? Why decrease the value of both entries when you could do it to just one, have the second player's item sell quick, leaving your own to be the two cheapest entries (or just the one) at a higher price.
