I live in a dense European city and all I ever do is order groceries online. I can order larger amounts in one go, so, batch order once every two weeks or so.

Instead of having to fight with a machine to give back my empty cans/plastic bottles, I can just give the delivery person a crate and get my money back.

Doesn't capture all my groceries, I love biking or walking to a smaller shop on occasion, or if I have a specific craving, but 90% of my groceries is delivery.
