I want to participate in the secret Santa event, and I know it says that the minimum required value is 1 refined, but I want to know something. Do people tend to give more than that? or does everybody just give a 1 refined hat and hope somebody gives them more, because I'm not very rich and I don't want to make the person I get feel bad, and vice versa if I give 6 refined and get 2 from my guy. How valuable is the stuff people tend to give?
