I'm sure you've heard Chicago is one of the places where they will be trying out the new Amazon Go stores. At these stores, there will be no checkout. Instead, you scan the app and you will get charged as you leave the store. A system of sensors and cameras will track what you grab. According to new info, the new locations will be at Willis Tower and at 500 W. Madison next to Ogilvie Transportation Center. I'm excited to try them out!
