I'm certain drone delivery will be a premium service for some time to come, even with Amazon working tirelessly to do their own logistics the cost of purchasing drones, maintaining them, keeping enough spare batteries charged, etc. is not $0. I already pay $4 at minimum for next-day delivery with Amazon Prime, if they want to charge me $6 to get a kit of memory or a cable in 30 minutes instead of having to drive to Best Buy (and pay a lot more than $6 extra for) I would happily do so.
