We have officially arrived in the future, and we're not sure if we like it or not.
Amazon has launched its brand new store in the States, where don't need to queue for the checkout or even get out your wallet at all.
Billed as the world's first supermarket without checkouts - either human or self-service - Amazon Go in Seattle has been tested by staff for the past year.
The shop uses several ceiling-mounted cameras to identify each customer, and track which items they select, removing the need for billing.
Purchases are then billed to customers' credit cards when they leave the shop.
Before entering, shoppers must scan the Amazon Go smartphone app. Sensors on the shelves will then add items to their bill as each customer picks them up - and then deletes them if any are put back.
However, there have been some issues. The app apparently had problems with correctly identifying shoppers of similar body types, while children would move items to the wrong places on shelves.
Gianna Puerini, head of Amazon Go, said the shop had operated well in the early period, saying: "This technology didn't exist - it was really advancing the state of the art of computer vision and machine learning."
