None.What is your go to resource to buy on one vendor and resell in another one?
NPC vendors...should have made that clear, thanks for pointing it out.Are you referring to NPC Vendors or Player managed Vendors?
The buy price goes up on an NPC when you buy again and the sell price drops.. It soon gets non profitable.I don't think reselling works like it use to. I can definitely be wrong on this. Didn't they put a timer on reselling goods to the same NPC? And a limit to the amount of items an NPC would buy from you resource wise?
Its been several years since i tried.
