I stopped working there in 2019 and in the few years I worked there I never saw prices on the IT kit in the vending machines. The IT vending machines were one of the better ideas I've seen at companies I've worked at. Many companies would require you to open a ticket and have an IT person hand deliver the keyboard, mouse, or other accessory to your desk. At Amazon, you can just go to the vending machine, swipe your badge, and get whatever you need, no human work required.
How is that a negative? Seems like a more efficient way to operate a company.
