But they require real-estate, and in the end the ansolute shipping cost isn't terribly far from home shipping(in urban environments) , and at that difference, people prefer home shipping, in the US.

But parcel lockers are quite popular in the UK, Poland.

In the old days shopping online meant fast delivery because they were selling luxury items in competition with overbuilt brick and mortar retail. Unless you get that music CD tomorrow afternoon, supposedly you'll invest two hours in going to a music store, waiting in line, waiting in traffic, waiting to park, waiting for mass transit, waiting to find your new CD, etc. But it hasn't been 1995 in a long time.

The future will look like my existing amazon subscribe and save delivery, I get periodic deliveries of stuff like shaving cream and toothpaste and all that kind of junk at a huge discount in a giant monthly box and I'm sure amazon makes stacks of cash being able to predict demand into the future and balance across distribution systems. I even buy my looseleaf tea from S+S. So in the future shopping will only be cheap, or at least affordable, if you're willing to wait till the 14th of the month when you get your monthly giant box. Frankly if I had to pay shipping out of my pocket and I didn't have Prime for other reasons, I'd probably wait until my monthly shipment.

UPS spends a lot of time and money driving those trucks all over creation to drop off a tiny little package of nothing at my door, often multiple times per week. Note the USPS was talking some years ago about abandoning 6 day service and going to 4 day deliveries.

My gut level guess is delivery will be like peapod but not food. An amazon warehouse will collect large shipments from all over the planet for a month, then toss my months worth of stuff into an amazon owned reusable shipping bucket, then fill an amazon owned truck with an entire subdivisions worth of buckets, then an amazon employee drives to my subdivision and drops one bucket per house and picks up my empties, and says "see ya next month". Or maybe every week. Or two weeks. I bet people will select neighborhoods based on how often amazon (and perhaps the USPS) service the neighborhood.

Soon, delivery is something a neighborhood will get, not an individual. Just like picking up the garbage is enormously cheaper to hit the whole district every thursday than to dispatch a truck to my house every time I fill one trash bag.

Finally you have the 1%er meme. As the last of the wealth concentrates at the top, you can't have billions of dollars in infrastructure for a quadcopter drone to deliver nothing important to a couple rich people at crazy expense without that world also being full of a hundred times as many people getting wood crates of rice delivered roughly monthly. Perhaps by horse carriage once the cheap oil runs out.

The partial agreement I have with you is the franchised pizza company a block from my house currently for insurance and licensing reasons cannot accept packages for me at their fancy truck dock. That'll change once the owner gets hungry enough for cash. Right now retail establishments, especially chains, are very silo'd and pretend the world outside their franchise or suppliers does not exist. When they get hungry that'll change. The only question is how it'll be financed. So my entire neighborhood uses the pizza restaurant or dive bar as their delivery address... do they rely on me leaving the waitress a tip or buying a round of drinks when I pick up my packages or do they extort money from the delivery company or the sender or maybe even me?

An interesting example of the future being here already is I keep trying to buy into a popular local CSA that delivers to my local food store and I always fail (probably popular because they're awesome). I'm not even sure CSAs are legal in every state. But the future is already here for CSA organic produce, if I ever get to buy in my delivery point is my local independent food store. (I'm told the food store is making fat stacks of cash off the CSA, empty cooler space makes them no money anyway so theres no loss, and people who take possession of heads of tend to buy salad dressing from the store, store sales are booming, etc)
