Tickets to those who donate makes a lot of sense. I saw some mentioning this in other comments…. Truth be told there is a war on metals among other alternatives to fiat. It’s just going to be harder as we go. Unfortunately this will be almost impossible in a few years. Sending silver overseas or rather across boarders. But I’d in future make sure everyone sends with tracking. I think it’s odd and quite foolish to send something without a tracking number. I’ve never heard of an option without tracking actually. When shipping internationally I mean. His is just basic common sense. Then on the two parties agreeing an alternative prize , that’s fine as u said, two consenting adults. But yea every participant should be given tracking number as part of the deal.
