This Monday Amazon opened its first cashier-free grocery store allowing customers to pick up their milk and eggs without having to deal with a queue, register or cashier. The trial store is conveniently located in downtown Seattle at the bottom of Amazon’s head office tower.

Shoppers enter through a turnstile after scanning the Amazon Go app from their phone. After browsing the aisles they’re then free to head towards the exit, their Amazon account is charged for the items they have purchased as they leave the premises.

The store’s unveiling is nearly a year later than originally planned but has been met with great interest. Customers have flocked to the new high-tech convenience store although there have been some teething overcharging/undercharging issues.
