A lot of people don't actually want or need 30minute delivery, and are perfectly happy with Amazon's free delivery that takes a few days. I can get two hour delivery here in London, but I've used it once. Amazon could get a product to a local centre, then instead of sending a van out driving all day going to one customer after the other, they'll hit a few key locations near multiple customers and launch drones out to serve them at the same time.
