 Money orders are a declining business for the USPS, as companies like PayPal, Venmo and others are offering electronic replacements.From 1911 to 1967, the Postal Service also operated the United States Postal Savings System, not unlike a savings and loan association with the amount of the deposit limited.A January 2014 report by the Inspector General of the USPS suggested that the agency could earn $8.9 billion per year in revenue by providing financial services, especially in areas where there are no local banks but there is a local post office, and to customers who currently do not have bank accounts.
