Interesting. I wonder what the business model is. Advertising? Subsidy from different stores? I would be interested to hear from the owners. What was the inspiration and what problem does it solve? But a few things. I don't see the real advantage of this over pen & paper & talking. How much on average could it help me save? Including travel time. I don't know about anyone else, but my shopping lists are open to change depending on what's available, in season, and how much time I have to shop.
