I'm waiting outside Oaklyn NJ post office. They are going as slow as can be. The line goes outside, will post office still.close with people in line outside?

Yes unfortunately

main post office facility in bellmawr is a good place to drop off your packages and mail after normal business hours as it is a lobby and can be dropped off 24 hours currently. but Oakland as you found out will close.

It will close. But the post office on Benigno Blvd in Bellmawr is open until 7.
