- RRRyanDec 13, 20255.0For a small town this post office is busy they do make mistakes but how much Sidney has grown it’s understandable I feel they take care of the mail the best they can and customer service is always good
- TWTreydan WipfDec 9, 20254.0Personally have never had any problems. Packages do arrive quite late into the day (7PM) which is a mild annoyance but I'm sure it's just a staffing issue.
