I guess you could discard less perishable products if they were moved around for use.
Listening to a couple minutes, it sounds like they talk about expired medicine. Great. In any case, I don't see that there is really much of a market for moving 4 pounds at 60 miles an hour in the US. We have decent roads everywhere and the resources to have extra things where they might be needed.
A concrete example. Like I say, I live in a region that is larger than Rwanda, with something like 1/75 of the population density. There is a hospital with an emergency room in town here, the regional hospital is about 55 miles away in a straight line, a 75 minute drive if you don't speed, and then a real city is about 100 miles away in a straight line, a 2 hour drive if you don't speed (and it's similar for most of population in the region, living close to an emergency hospital and not all that far from a larger hospital).
What logistics are you going to institute where frequent small deliveries make a difference compared to regular vehicle based deliveries?
I guess if it is cheap it can be used for home deliveries.
