I called about a package that was mis-shipped to this location. I called and talked to one of the employees and she was super helpful and looked my package up for me. She was extremely helpful and made my day better by assuring me that my package would be there in a few days and it was not lost. Very great experience!!


I did not know that the "US Postal Service" could just post a generic note that they left early? I went to the St Mary PO to pick up a Certified letter and found the note. REALLY?


My Christmas lights I ordered were stuffed in my mailbox so hard I had to get a flathead screwdriver to pry it out and half the bulbs were busted why didn't the lazy driver I've complained about many times before leave the pkg at my door. My order was damaged because of this I've complained numerous times
