I had been out of town for about 3 weeks, during which time I had ordered a LOT of vape-related stuff. Since I'm always gone, I use a friend's address as my shipping address. Apparently, I forgot to do that with one of my orders. It was sent to my apartment. I got a slip that said I had "a package" that was "returned to sender" after 10 days. No tracking number. No address. No info. No idea where it came from, or how much I paid for it, or if I'll ever get it back.

Called the Post Office. No joy. He said, "heh, heh, it was probably something you're not going to miss, anyway". :-x

I guess those tracking numbers are important, after all.
