Undercutting by a smallish amount or price matching is normal behaviour. I often see some strange people crashing the price of an item for no good reason which leave me scratching my head. Stuff for sale for 50k, some dingbat comes along and decides on 20k, people start piling under that, then another dingbat comes along and it's 5k... people start piling on under that. When I see dumb crap, I just pull the item. I can wait.


The other thing that grinds my wheels is people putting stuff on the MB for the same, or less they would get if they just vendored it. why on earth put someonething on the MB for 1 gil? sheesh. Why even bother with the MB if you can get the same price immediately?
