Yes Matt, you are right. You will never see your package. It is lost forever since it didn't show up when the emails said it would. No sense waiting to see if someone figures out they have a package they missed delivering, better to assume all is lost.
Four years ago I sent a package to my daughter in Kenya, Africa. I add the continent designation because not everyone is aware of where Kenya is, and the fact that her "zip code" there was the same as a community 45 miles from my location in Iowa didn't help her get her mail. An amazing amount went to Mason City Iowa before it went to Africa. Anyway, the first package I sent her weighed 25 lbs., and cost me $80 to send the cheapest rate I could get using the U.S. Postal Service. FedEx or any alternate carrier was out of the question since I wanted to keep the bill under $150. I never again sent her a package that weighed that much, and I never used anything but first class after that. That way she received most deliveries in between 2 and 4 weeks. She received that first box approximately 23 months after I mailed it, shortly before she was evacuated. Sorry to hear your delivery from China is a couple of days late.
