I mean, you still need a truck to get the item to the store...
Delivery is actually more resource-efficient if the store isn't within walking distance of its customers. If instead of making 10 people get in their car and make a round trip to the store/warehouse, you put 10 packages in one vehicle and deliver to everyone in the same neighborhood with one trip, you're looking at an order of 90% less wasted emissions.
I'm actually not, but the person I was replying to clearly was given the "three states over" comment. I explicitly specified the statement was conditional on customers not being within walking distance.
Peak east coast US! You can travel three states of distance and back in a day or less on the east coast.
Three states over and back would be a day or two minimum, but potentially nearly a week on the west coast. (Depends on start and stop locations obviously, but if you start from eg Portland, three states over could be the Dakotas).
