I do most of my groceries through Ocado, and their warehouse operations are almost fully automated[0], but then on the delivery front I can only assume they staff much more generously than amazon, because their delivery drivers are always much more relaxed than Amazon drivers, they're quite happy to have a chat while unpacking, and often call saying they're running early and ask whether it's ok to arrive before the delivery window.
