The United States Postal Service hasn’t delivered regularly on Sundays for 101 years, but a force known as Amazon managed to persuade it to change. The company and USPS announced on Sunday they’d made an arrangement to deliver Amazon packages seven days a week, though they haven’t made public the financial details. While the USPS loses money on first-class mail, the New York Times notes, it makes money on package delivery. But it wouldn’t say whether it was open to deals with other companies. For now, Amazon gets Sundays all to itself, starting in New York and Los Angeles, and expanding to other cities next year. It’s going to be a while yet before that lone mail Jeep goes bouncing down a country lane to deliver a copy of Rush Revere and the Brave Pilgrims a day early.
