Picked up this time.
Amazon driver right outside

I'll back this up. Answered the call yesterday, opened the door and saw the driver with the phone to his ear talking to me. It's Amazon.

How is Amazon going to cope with theft of delivered packages if those packages are delivered by drones?

Thanks everyone for the update and it makes sense as moments later, after the call, I got a text message saying my package couldn't be delivered, which is strange as I've never had Amazon call me before about a delivery before.

I... don't know? Kinda the same if a man or machine puts it on your doorstep, no?
But I work in insurance, so I cant really help you.
