I've had to track down a $200 record that I shipped. The buyer wasn't even stressed out about it, but I was. It literally went from an "out for delivery" to nothing. They couldn't track it and this went on for a couple of weeks, minimum. I called USPS and a women was pissed off at me for contacting her, claiming that they had it at some other facility, and she was threatening to mail it back. Why not just deliver it if you still have it and never did. I called the other place she told me to and they said they didn't have it. It was a mess, but... somehow, we finally got it to him.
