It was “Save the Post Office Saturday” this past weekend. Thousands of people across the country gathered to demand that Congress shore up the US Postal Service. According to Move On, the USPS revenue comes entirely from postage and services. Not tax dollars. Revenue is expected to be down by 50% this year, so the agency may well run out of money within the next few months. Move On says that while Washington argues about how to support the post office, FedEx and UPS have already gotten stimulus money .
