what you're saying is similar to the taxi industry pre-uber, they had similar attempts but they could never do anything to undercut their main existing business. The service experience with grocery stores that delivery (similar to taxis) is poor and the cost is higher. I'm thinking a pure virtual play can at least compete with brick-and-mortar. Cost, and being able to browse visually and pick specific items are the two main obstacles, which today's tech can solve, albeit with a high startup cost.
