People tend to check in during these times:
Print your postage at home and skip the line. Labels online at USPS.com or use 24/7 automated kiosk. Theres a 24/7 package drop off bin that fits small/med boxes. FedEx drop here as well outside
Be prepared to wait, always busy
Always heard it's really busy but 420 on a Tuesday afternoon was very slow.
Quick and knowledgeable staff! Best post office around!
Just say no to overnight and yes to 1st class. Snail Mail.
