Warning to my fellow Oak Park residents! I just learned that if I purchase a mailing label, either online or from the kiosk, and then put that labeled package in the collection box next to the kiosk, the Post Office never scans it in. They have no way of tracking your package. However, if you leave your package in the pile on the main counter, they will scan it in. There is no signage to this effect anywhere. The package I mailed Tuesday, using the collection box, will not appear in the system until it is delivered. If it is lost, it is lost forever. Use that pile at the counter!
