I have mixed emotions about this. Fed Ex has never let me down on an Amazon delivery, they just stopped ringing doorbells to save a second and a half (so I never know exactly when it arrived unless I check online). Fed Ex made $850 million on Amazon deliveries in 2018, but that's only 1.3% of all revenue for that year, so who needs it! Ha!  And the US Post Office usually doesn't let me down either (but they stuff large packages into small P.O. boxes). I guess they'll still use UPS...?

Amazon is actually starting to build their own fleet of delivery vehicles. Then of course we are in the age of the drone and that will become a reality one day.
