The RL runners are up to radio now, that means that the demand for copper wire and copper ore is high. I can't find any on the mkt.
Put your copper ore and copper wire on the market for max price - it will disappear fast. It will also cause the max price to rise. Then you will get a nice fat profit off of these materials 
I am now looking for a steady supplier of copper ore. I'll buy for max price up to 1,000. Above 1,000 I'll pay normal price.
