Yes, there is a kiosk inside to mail your packages on the weekend at this location it is called a self service kiosk on the usps website.
Ive never heard of that. Post Office delivers on weekends,even Sunday,but dont think they have hours on Sunday. you can always go to Staples UPS drop off in Berlin,on your way you pass a Post Office on Rt 561. Good luck
