Amazon already does same-day delivery in more areas than you're likely to see drone-delivery in the next 5-10 years.
In most places, the fancy technology has zero advantage over employing a handful of couriers. Exceptions would include extreme geography or traffic conditions.

Straight line delivery and Amazons ability to mark a job finished more quickly are both valuable in any area.
If this means I can have something delivered in 45 minutes, or maybe 20 minutes!, they can charge a premium for that. Otherwise I wait for the big truck to bring it by within 2 days and it's free. Right now there is no solution at any cost, in my market, by which I can order almost any product from Amazon and have it within a few hours.
