My optimistic side is imagining a truck filled with a small town's worth of nutrient-rich groceries, making one trip to replace dozens of individual trip to a less-than-convenient grocery store.

My pessimistic side is imagining a truck with one or two people's worth of shitty "American" groceries, making the same trip they would have made to a grocery store down the street.

I feel like the reality heavily leans to latter, but I only have anecdotal data to back that up.
