I love Amazon Go. Go in, pick stuff, get out. Using the palm scanner I don't even need to take out my phone or wallet. Great if I just want a quick snack or drink.

My only issue with them is the way they cycle their inventory. If I want popcorn chicken, its a gamble if they're gonna have it or not and seems semi-random. The breakfast options completely suck too.

But I really like the store's concept.
