It’s Amazon Prime Day, for shoppers living in the US and a handful of other countries. On this day, users who subscribe to Amazon Prime membership are promised 100,000 special bargains by the e-commerce platform, launching the kind of purchasing frenzy that saw more than 34.4 million items sold last year.
To move all that stuff, Amazon has a sprawling logistics network, designed to deliver most Prime products in just 48 hours. In some warehouses, known as “Fulfillment Centers,” robots have even been introduced to shorten the the “click-to-ship” gap to just 15 minutes. For a peek at the sheer scale of the company’s extraordinary day-to-day operations, you can actually visit six real warehouses across the United States—or just take a look at the dizzying photos below.
