Just want to share what happened to my package. My parents live in Germany.
They sent to us a package with several nice art books and some children toys and clothes. When I received the package it had no books at all. It had the clothes and toys my parents sent along with somebody else's stuff (a scarf, wallet, and socks in a gift wrapping paper, a soap, a broken Christmas candy). The package was opened and retaped.
The label on the package clearly says its weight was 8.5 kg (over 18 pounds), and the custom declaration says "books". Obviously the package's weight is much smaller now, around 7 pounds. The USPS tracking tool shows that it arrived to ISC NEW YORK (which is supposed to be the customs) and was there for 12 days. I believe somebody in the ISC opened a bunch of parcels at once, went through the content, then just stuffed the things back without paying attention.
I filed complaints on usps.com and on postalinspectors.uspis.gov but I doubt it will help.
It is not that the lost books are super expensive, I just feel sorry for my parents, they wanted us to have those particular books. If somebody recognizes their lost items (a scarf and socks in a gift wrapping paper, a soap, a broken Christmas candy) you can contact me on this site with a description and I will sent it to you.
Monetary Loss: $50.
