Lesson learned from using USPS
Last December i sent my daughter a gift using UPS. Never more. They left the box on the front porch it was stolen. I resent similar gifts using USPS. and instructed her to get a po box. USPS mishandled the box perhaps using it as a football. Anyway it ended up in Atlanta, she lives in Seattle. The recovery center ended up with it. After i discovered where it was and working with the post master at my local post office i got the box back after three months.
The lesson i learned was first put a letter in The box with an address where the box should go. The recovery center gets the box because the label was destroyed if they have a tracking number then there is hope. They will open the box looking for an address. Lesson two use a sturdy box and cover your label with clear tape. I had sent her a three hundred dollar quad copter and a few other items some of which were missing when i finally got it back. It was insured but good luck with that.
