So, this is the wave of the future. Now, how do I make money on this, apart from buying Amazon stock or starting a drone company (which are going under in droves, I should add)? Is this going to be a first-past-the-post thing? I can't see how any other retailer will be able to compete with this, once they start rolling it out, and assuming they won't be offering DDaaS (drone delivery as a service - you heard it here first folks). I'm not sure how much the marginal delivery costs for Amazon are going to be, but this might give them a 10% (!) increased profit in an already very low-margin market? That would obliterate most competition.
