I need to know what the upcoming delivery situation is for 1825 Tower Avenue Superior Wisconsin 54880 . I was told it would be in back and I would have to attach a mailbox to the back entrance of building since there is no place along alley on this property. But no one has gotten back to me. Please let me know soon. Thank you


My mail has not been delivered all week. I got a notice today from Amazon that the mail carrier was unable to access my front door walk way, my sidewalk and front porch has been cleared so this is pure laziness on the carriers part. This is not ok and I will be contacting the post master Monday. Our old mail carrier would have never done this. People just don’t want to work anymore.


My mail carrier sucks ...I use to order online alot ... I very seldom got my stuff I stopped ordering ... Well my sister mailed me a package she paid for a 2 day delivery ... It. Shows my package was delivered March 6 2019. WAS NOT DELIVERED TO ME OR MY MAILBOX ... I called the post office ... The person that answered the phone says ..ya ok I will ask your carrier ... Ok .. I don't know why it's so hard for me to get packages ... I hate the thought of my mail person keeping my stuff but ..I do wonder... My brother in law mailed a package at Xmas time. ... Guess what ...we never seen it ... I'd like to.know what to I have to do to be assured my mail is going into MY MAILBOX ....


I live in the town of superior. I order things on line as I am disables. This morning after a terrible storm, my packages were laying on the ground by my from door wet. I never use the front door and there was mail in the box today. The packages were wet and blown on the lawn. I do not have a dog and deliveries are made to the back door.. If this service is paid by the vendors, I expect you to deliver things if Im in the house.


Wonderful customer service! I have recently moved from Superior and my change of address had expired and somehow one of my packages got sent to my old address. The carrier, however, remembered me and forwarded my package on to the new address. I was so worried that someone would steal my package. The postal office in Superior gets five stars. Thank you so much!
