I’m buying Copper Ore at 17 copper each (200 total | 34 Silver) and then selling them at 20 copper (200 total | 40 Silver). Which should be 6 Silver difference minus 2 Silver listing fee, for 4 silver profit. However, after I sell 200 copper ores at 20 copper each, I only make 36 Silver (For 0 net profit). Where did all the money go?
