Imagine you are in a rush and need to go to the grocery store. With Amazon Go, you can walk in, get your stuff and walk out. In fact, they call it their Just Walk Out Shopping experience or Just Walk Out Technology.
When you walk in, you use the app to check in (kind of like when boarding a plane) and then do your shopping. Forget your bag? There are plenty of reusable bags for purchase. You will also need an Amazon account.
They offer many ready-to-eat meals and snacks. They want to focus on making healthful meals.
They currently only have one store open to the public in Seattle, WA open 7am-9pm M-F. They do have people in the store to help you, stock shelves, etc. The store was opened last year for its Seattle employees while testing. It just opened to the public recently.
