Undercutting

[chocomaid]

It is when the retard undercut you soo low where you can make a profit just selling the item to an npc. I've seen people selling things on the AH for 1 Gil when you can just npc it for 4-20 Gil.

You are talking about a totally different topic. In this case, OP is just complaining that someone undercut his highly overpriced shiny item. Note that nowhere that it states that "you should sell it at this price or you are an idiot". Everyone can choose to sell items at whatever price they choose. Are they making a profit? Are they losing profit? That's their problem, not mine, not yours and certainly not the OP.
