So it seems that most people assume that this kind of shop is a replacement to major grocery stores. I dont think that this is what their initial customer base is going to be. I see this more inline with "Fresh & Easy" kind of markets where on the go customers can just stop by for a quick bite or a quick pick up of resources like a 7/11 or something similar. I can see that they may want to expand to supermarkets but I think this is more addressing the quick easy supermarket market and focusing on easy pickups rather then full fledged supermarkets for all grocery needs. I may have missed something but that would be the most logical and successful way for Amazon to introduce this technology.
