Well, the story now has a happy ending!!

I received a phone call about 15 minutes ago from a neighbor a couple of streets over. She just now checked her mailbox, and my package was in it with her mail. No one signed. The slip on the package required a signature, but I guess USPS is getting sloppy like UPS and others sometimes are. Now that I have the order safe and sound, I'll give USPS the riot act tomorrow - wrong address and no signature!

Everything is intact, even the bonus meds. I am so relieved. Yesterday I think my imagination just went wild after reading the USPS tracking info.

Thank you again, everyone. I appreciate your help and concern.
