How is Amazon making money overnighting me deodorant for cheaper than what I can buy at Safeway Your local safeway had to have that deodorant shipped at some point, too. Then they had a shop clerk unbox it, put a label on it, place it on a shelf, eventually drag it over a scanner and (in america) put it in a nice brown paper bag for you. The brown paper bag, the scanner, the shelf, the label, the clerk, and no least the brick & mortar store surrounding all that costs Safeway significant amounts of money - in addition to the truck that initially shipped the deodorant. Amazon pays only the truck.
