Hi.
I post two Screenshots, hope you understand what i mean. Its kinda German.
How it works: If you want to buy Ghost Iron Ore and its too expensive, just put one Ghost Iron Ore into the Auctionhouse, way more cheap. Other PPl will undercut it.
Than you will just buy. Your one piece of Ghost Iron Ore won't be bought fast, because who needs just one Ghost Iron Ore?
