PHOENIX -- What goes on behind the computer screen on Cyber Monday can be seen at the Amazon Fulfillment Center in Phoenix.
The 1.2 million square foot facility has over 1,500 employees working around the clock every day to fulfill orders.
Last year, Amazon shipped 36.8 million items on Cyber Monday. Customers were ordering items at a rate of 426 items per second.
"We actually think this year is going to be even bigger so we're ready for it, we're stocked up today. We're busy here, we're really excited about it," Sarah Gelman of the Amazon Fulfillment Center said.
The center has anywhere from 17 to 19 million items according to Vince Hayes, the Learning Coordinator.
"Once the order makes it to our fulfillment center, it is charged, that's what we call it, where it's actually dropped in to a scanner," Hayes said. "As a picker, if I were picking, the system would then tell me where to go."
Amazon is having new deals every 10 minutes on Monday and other deals throughout the week as well.
The Kindle Fire is on sale for $100, and later this week Amazon is offering 50 to 70% off select children's outerwear among other deals.
