Big shout out to the Winterport post office, and John in particular. Understaffed but working hard and delivering packages on the Saturday of a holiday weekend. Hats off to you all, and thank you!

I would stop here periodically whilst visiting my mom for the summer.
Being from out of state, seems I was always mailing something back home.
Service was always friendly, no complaints. There might be one or two in line ahead of me, but not often. If there were, things moved along pretty quick.
It's a small, little building but easy to find. Easy to get in and out of, too. Right there in the main drag - you CAN miss it tho, if you're not paying attention !! 😄
The offer the usual services as a part office does. They may be small, but they still do a great job !

My auto parts were shipped to the post office by mistake. They were very nice, and held them until I got there.
