I see the idea and. have thought about this myself - especially know - how do we support the small businesses in our communities even though we can get cheaper alternatives from the giants. How do you promote this type of purchasing patterns. I guess this is similar to what Etsy has done with handmade goods?

You could have a small city by city curated site that sells on behalf of those businesses - though you aren't going to be able to add a lot of margin on this. Since they will just go to the local business to purchase. Maybe what a local business needs is a better platform. You could setup a curator in each city to manage the relationships. For delivery - I guess you could get a uber model going and just drive to locations for pick up and delivery vs standard shipping.
