I doubt they would do this as it would reduce their already razor thin margins. And there is little incentive for them. I don't think many people would be willing to shop like that either, since the mindset of a purchase like that is sort of the anti-Prime - "just let it arrive whenever", as opposed guaranteed 2 day air. Long story short I just don't see that as a very Amazon-like move. That said, I would probably use it once or twice a year if such a feature existed.
