Hasn't happened, won't happen, can't happen. As soon as the get "completely built out" margin will only continue to suffer. The reason they don't make any money is because they don't price their goods and services for profit because they want to grow at any cost. As soon as they price in profit for their goods and services, demand will decline. Margin may improve then but sales will decline. A better mousetrap has not been built. They do not have a more efficient model than any other retail organization. It is slightly different than WMT but less efficient. Instead of paying low earning clerks they pay low earning warehouse employees. Instead of paying high rent they pay high salaries to engineers to work on website optimization and infrastructure. Get it? 17 years in operation and the margin only declines each year. No end in sight.
you seriously need to learn about margins......when aamzon is completely b uild out margins s will increase and not decrease...their revenues will keep growing worldwide ......remember their investing in cloud technology......im suspecting they will introduce video streaming to compete with netflix
