I feel your pain...
I had a very expensive rare replacement note damaged during transit from South America. I had been hunting for this particular note for close to a decade. The seller literally just placed it in an envelope and shipped it to my residence.
My first reaction was extreme anger followed by sadness once my blood pressure came down.
From that point on I`ve always asked the seller(s) to post in a hardback envelope...
P.S - I received a full refund in exchange for a stern verbal lashing...lol
P.S.S- Still haven`t found the note..
