I went through the Amazon Go store last summer in Seattle. You are allowed in through a turnstile after scanning your Amazon ID. My son scanned his card 4 times for our party to enter. You literally just walk in and take things from shelves and walk right out the exit. There were no employees present. I grabbed a can of Diet Coke and it was only .60. Yes, everything was cheaper. When our party of 4 met back up outside my son checked an app on his iPhone to see what everyone bought. It was accurate. I know I picked up a few items just to read labels before returning items to shelves too!
It was awesome.
Anything that simplifies our lives and make it easier is progress in my book.
