For picking it's already doable. It's possible to build automated warehouses that could pick and pack orders ready for delivery or "click and collect".
Delivery is indeed the difficulty and the solution depends on the coming of age of self-driving cars (level 5). My experience of ordering online from supermarkets is that a guy drives a van around and takes your order to your front door. In suburban areas (i.e. houses not flats) we can imagine self-driving vans stopping in front of your houses and letting you collect your order like a vending machine. This is not possible now because there are no self-driving cars but the instant they become commercially available I bet this will quickly become the norm.
Automated warehouses plus self-driving cars enable a fully automated process from order to delivery. I'm sure we'll get there.
Drones are simpler to fly autonomously but I don't think they are practical for delivering 10s of kilos of stuff to residential areas.
Self driving will take decades before it becomes viable in developing countries. The state of driving there is very different than what the algorithms are being trained for in the US and Germany. We might have to wait until quantum computing is a thing.
