You'd be surprised. I don't think the large majority of the population thinks about the logistics involved at all, except insofar as it directly concerns them (ie. the last link in the chain, or when there's a problem in fulfilling the order). Retail is an abstraction that conjures products into consumers' hands as if by magic. This permits them to stay conveniently ignorant of the ugly parts of the supply chain, whether it's torturing and killing animals on factory farms, inhumane working conditions at a sweatshop in a faraway country, or the labor-laws-dodging gig economy of couriers and fulfillment center workers.
