It's bad all over. I was gifted some material from my Dad's AAF base in England, and all was great until it was set to go overseas to the US. There it sat. I had a tracking number, and after a while (3-4 weeks) I contact Royal Mail. After taking a week or so to respond, I got a vanilla letter saying "Golly, gee whiz, we don't know what happened to the package." I contacted the small museum that sent it, and they got in touch with RM, and since so much time had elapsed, they refunded the shipping charge to them.
They didn't have to, but the museum sent more stuff, this time by FedEx, and it arrived in 3-4 days.
Three months later, I opened my mail box, and there's the original box, with a sticker on it from RM stating that he package cannot under any circumstances be put on a plane. The only thing I can figure is that it contained 3 linked .50 cal casings that the museum had recovered from the ground at the AAF (and had given to me as a thank you for a nice donation). It was just the casings (I figured it was the end of a test link belt for the armorers to check the functioning of the .50s) and some weenie at RM saw the x-ray and panicked thinking they were live rounds.
