Shopping at the Go Store is much faster. When you're grabbing a single item you can have times of ~10 seconds. Grabbing more items and you save more time by not having to check out. No checkout, no lines, no figuring out why your phone or card isn't accepted, or what error message is on screen etc. In and out as simply and efficiently as possible.
I wouldn't say it is revolutionary, but it does cut down the time it takes to go shopping. It's like a perfect version of self-checkout.
Another, more subtle feature is that I never wait in line because I have trained myself to never go at peak times. I waste a certain amount of time thinking about it.
That said, I find the idea of a cashierless store super-creepy and will be among the last adopters.
It's nice that you save a couple minutes, but I doubt it really has much impact on your day.
Or was that all on Thursday morning?
I absolutely guarantee it will change your spending habits this coming decade.
I'm not sure if there's a way to understand until you experience it being walking distance from your office.
I suppose it is not so likely there will be a store in walking distance the next few years.
