This year Cyber Monday has been the largest ever, with consumers spending $7 billion. But how does Amazon handle all those online sales?

Since the start of Monday, hundreds of workers have been working 22-hour shifts just to keep up with the demand at the Lenexa facility alone.

“I’m pretty confident we can get those items to you faster than you can sing the 12 days of Christmas!”

Amazon has installed new technology in their fulfillment centers to make it easier to track items on the miles of conveyer belts and uses robots to move items within their warehouses. Amazon has been able to sort and package your items in record times so customers can receive their items in two days or less.

“They are certainly part of the team. They don’t replace anybody, obviously, but they do work really, really well with our associates, allowing our associates to be more efficient.”

The top selling items this year are the AncestryDNA kit and Amazon Echo Dot.
