Your comment points to the solution: that of increasing retailer specialization, and the need for local stores to focus on items that are not easily purchased through mail order. The corner grocery in an urban neighborhood doesn't compete on price with the supermarket 10 blocks away. It competes on convenience. I'm not saying the idea works, but there is more to it than just mapping all existing old school retail establishments into a search engine.
