DeJoy has large investments in a shipping company that contracts with USPS. He also has large investments in Amazon. According to my hair stylist who also works at the post office sorting mail, Amazon has a contract with USPS for a flat postage rate of $1.90 per package. There is also a Sunday delivery contract. Amazon pays the $1.90 postage plus the carrier’s payroll, which is usually overtime at time and a half, when packages are delivered on Sunday. So it’s beneficial to delay package delivery during the week and let Amazon pay for Sunday overtime.
