Some interesting possibilities here...
but delivering parcels for amazon really isn't one of them.
1) Major weight limitations
2) Where does it land?
3) How does it knock on the door for a signature?
4) How does it know to leave it in the garden shed if I'm out? And even if it does, how does it open the door?
5) How many people live within 10 miles of an amazon distribution centre?
6) And what about people living in blocks of flats? Does it knock on the window?
7) and the whole thing about collisions with trees, birds, power-lines, phone-lines etc...
Drones may one day have many uses, apart from firing missiles at Afghan children, but they won't include amazon deliveries.
