> You get free same day delivery. Amazon just greatly saved on last mile delivery costs. I'm under the impression this is something they're really trying to optimize right now. Not sure if it's everywhere but where I live in Cincinnati, Amazon is now operating their own courier service for normal Prime deliveries piggybacking on top of Prime Now drivers. When you place an order (on regular Amazon.com) you don't necessarily know whether it will come from UPS, FedEx, an Amazon courier, etc. The Amazon couriers don't seem to know that it's not a Prime Now order and that the delivery time isn't known in advance to the customer like it is with Prime Now, as they show up midday and call you (from an unknown number) anticipating you'd be at home and asking you to let them in the gate. One unexpected problem that emerges here is that the standard delivery service courier for a route is regular and that one person can be given a gate key; much harder to solve that with dozens or hundreds of couriers.
