Trader

A trader, unlike a merchant, does not sell and buy goods at a fixed price, but depending on supply and demand.

You may even find a trader "out of stock" if there is very little supply.

Prices have a lower limit (the same price that you would get if you sell the same good to a merchant, but are open end. Prices for certain Superior Runes have gone up to almost 100 platinum at one point.

These are the traders in the game:
