What's the deal? I lived in Libby for nearly 30 yrs and this was always an awesome post office. I don't live there for the last few years now though. I had a package mailed to a dear friend from a business ( not Amazon). It showed it was delivered to their PO box on July 1st, yet they have never received it not a notice for it!. I checked the business that mailed it and verified it was labeled with the correct correct PO box number. I've have literally tried calling the Libby Post office number 13 times today alone. I let it ring for over 3 min and was disconnected each time.
I finally just put in for a lost package with the main postal service. Sad that no one can answer a phone there too talk to me.
Very sad. Now I have to spend the money to purchase this gift again and send it to my friends street address. Hopefully the Libby Post office won't screw that up as well.

I love this post office!! They are timely with our mail and packages and always have a smile on their faces. They help us whenever possible to make our experience as easy as enjoyable as it can be. If you have a bad experience here, it’s own your fault!!! Thank you very much for all your hard work and kindness.
