Amazon is not know for posting operating profits, because they plow funds back into new research and businesses. But they most definitely operate with gross margins on everything they sell. Update: in FY2014, they sold $89BN ($70.1BN in products, $18.9BN in services), and their cost of sales was $62.8BN. I am pretty sure that their margins are razor-thin in retail, but the service side had higher margins.
