I have a couple ideas in mind on what we can do to sell our ores

We could created a new store were we can go to the shop and sell our ores like the NPC in TAU and have the % rate change here and there. We can also buy items from them but the item changes randomly and make stock have a limit like guns will be 1 per user and random item will be like 3 or 5 per user but have items update every 30 to 45 mins

Or

We just place a NPC nearly the Mining area and just sell ores
