The folks at the Buffalo, MN USPS are outstanding. I sell products through a website at Etsy.com and ship hundreds of packages every year that begin their journey at the Buffalo, MN USPS. During 2021 all my packages have departed promptly with no problems and I have experienced 0 damaged product/packages. Congrats to all the professionals at USPS Buffalo, MN!


We love our Post Office and its staff. But we keep getting Emails indicating that there is some effort to close it and other small PO's. If that is true, what can we do to stop it and help the post office get back to how it was before DeJoy became US Postmaster???
