Amazon is expanding its Go convenience store to two more locations

Amazon debuted its first Amazon Go location at its headquarters in Seattle in December 2016; it opened to the public in January of this year. In case you missed it, the delivery behemoth unveiled a store in which shoppers don't need to worry about checking out.

That news comes from the fact that the internet retail giant has listed Amazon Go store manager positions for Chicago and San Fransisco on its jobs site. As many as six stores could open this year, according to Recode. "Come join Amazon Go and help our customers get good food, fast!" the listing reads. Overhead cameras keep track of what a customer buys and charges them after they leave, the Tribune said.
