I'm sending a letter to Germany (and a few other countries) and I'm including a self-addressed stamped envelope in it. When the German person sends it back to me, do they need to add more postage to it? It's currently stamped with a .39 stamp. Should I not bother with postage at all if they'll have to put their own stamps on it anyway?
