Is that 3 cents after the money FedEx makes that goes into paying for the courier, the truck, the fuel? FedEx isn't paid 3 cents per pkg, it clears 3 cents after it's other expenses. And nationwide that profit adds up. If it didn't work for the company's accountants they wouldn't be doing it. Now if that isn't worth it to Ground contractors to clear 3 cents a pkg ok, point taken. But even Amazon knows it can't push for 2 cents because no one will deliver their pkgs if they can't make money doing it. Which is why they're looking to deliver their own pkgs as much as possible.
