- ADAnnette DuCharmeJun 16, 20265.0Within walking distance. I am old and keep driving to a minimum
- MRMary RamirezFeb 14, 20264.0They do offer money orders, and I’m glad that they do your office is convenient since I live near the downtown area and currently no transportation to the main post office. However, that being said I wish they had Saturday hours open for those of us who can’t make it to the main post office on Saturdays because bus routes don’t run regular hours which makes it difficult for others that use public transportation to get to the main post office on Saturdays. All in all, I think you’re doing a good job at this post office.
