This Post Office can get very busy... especially around lunch time and after 4pm. Best time is in the early morning.
Friendly staff and they never rush you if you have a weighed package going out.
I use the free priority boxes for shipping and I get my labels online (discounted price), but they only carry the Flat Rate Boxes and Envelopes for regular and express priority at this location. Also no automated machine to buy stamps, weight your package, etc...
