I'm more concerned about whether the store system gets my order right than whether I do. What if it, e.g., mistakes a can of soda for a 12-pack? Three hundred times on the order?

FWIW, I've been using Amazon Go stores regularly for a while and have never had any issues.

There's a link to dispute the receipt should something happen, right on the receipt itself. Now this is specifically Amazon Go app, but I would expect it to be same for other retailers.

Edit: I see that this is a little bit different than Go stores. It's far less convenient, but you can still get the receipt in your email by visiting a kiosk it seems.

I wonder if Amazon can offer some kind of good-will insurance here. Like “if our system mistakenly looses a customer money, we’ll cover it for you.”

Agreed. I feel like the point of this is to separate the buyer from the notion of total price. They may as well change the unit from dollars to "credits".

This is unlikely to happen. Shelves act as scales, and there is a big weight difference between 1 can and 12 cans.

That would be very unlikely and easily reversed based on video data.

Would it?

>easily reversed based on video data

That suggests a level of effort from multiple parties well in excess of the typical "look at item; look at receipt"

Given that the exact timestamp of when the system thinks an item is picked up is known, it should be trivial to review a 5-second clip and flag it as correct or not, training the ML model at the same time.
