In theory yes, in practice Amazon has a lot of catching up to do. I don't know about the situation in the US, but by now every big food retailer in Germany has a delivery service, ALDI included. These food retailers already have all the supply&logistics in place due to their physical stores, the delivery business is just an extension, all of it often heavily sourcing from local producers. In the long run, these companies can shift their main business to deliveries, turning their retail stores into mixtures of store and distribution center. In that context, I don't see how Amazon will easily be in a position to get similar products, at similar prices, without having at least some physical retail presence. They got the logistics down, no doubt about that, but I think in terms of actually sourcing fresh, and local, produce the established food retailers have quite an edge on Amazon.
