Easy way to fix this problem is for them to take the same tool in place used for barter and add it to the trader section. This would allow people to sell an item in exchange for another item. Example - Selling 1 naggy cloak for 1 krono. or selling 1 krono for 1000 of whatever item you think is re-sellable for the item in question. This would allow goods to be traded in a new way becides the use of currency avoiding the hard limit cap while still allowing the use of nobles for people wanting instant plat.
