I haven’t stood in line in the Post Office in years. I buy stamps online. When I need to ship a package, I weigh the box and then check prices online at USPS, UPS, and Fedex. Whichever way I go, I pay online and print a label. At UPS and Fedex, they may or may not be a line and they just scan the label and off it goes. At USPS, there is an outer lobby that is open 24/7 and I just drop the box down a chute or I can just hand it to my mail carrier. There is no need to stand in line unless I’m going to ship something international, and that is rare.
