This Is What It Looks Like Inside an Amazon Warehouse (Photos)

What happens after you click “buy” on Amazon.com? To most people, that’s a mystery. I flew out to Phoenix earlier this month to find out by taking a tour of one of Amazon’s warehouses — what it refers to as “fulfillment centers.”

I spent about 90 minutes inside the facility, and documented what I saw in photos. I had limited verbal interactions with workers during my visit, so if you’re looking for a detailed description of what it’s like to work in each role, you’re going to be disappointed.

But if you want an inside look at the operation that CEO Jeff Bezos recently referred to on “60 Minutes” as the “secret” to Amazon’s success, you’ll likely enjoy the photos in the slideshow below.
