Initially this will probably carry a significant premium over normal delivery. However, as someone who lives in a city, I can definitely see there being times when I would be willing to pay the premium. Taking a cab ride to and from somewhere can easily cost $15-$30, so it could actually be cheaper to have the item delivered by a drone if time is of the essence.
