Market

The Market is used to buy and sell resources to other players. There is no listing fee and no market tax.

Reselling
Since there are currently no fees and taxes at the market, buying cheap resources and reselling them at higher prices is easy and can be lucrative. The markets tend to fluctuate up and down throughout the day. Purchasing at the right time can pay off big when reselling later.

Undercutting
The market board places the lower priced listing first on the market board. Undercutting other listings by even 1 gold often results in quick sales (often to the tune of some moaning and groaning in trade chat for lowering the market price). But undercutting at the right time is a part of playing the market.

Cornering the Market
Very wealthy players can sometimes have the means to buyout vast amounts of resources and temporarily raise the prices. Opportunistic tradeskillers can sometimes ride the wave of higher prices and sell for a nice profit. But it often leaves most players simply having to pay more for the same resources. Watch out for when prices seem artificially high and consider holding off on purchases until the market stabilizes.
