Amazon is merely pushing the tendrils of predictive modeling down a level in their supply-chain. No, they're not going to actually deliver something to you before you order it. But experience tells them, through predictive modeling, that someone in your immediate neighborhood is likely to order more boiled peanuts in the next day or so, so they simply box them up, put them on a truck and once that truck gets to your neighborhood, they lie in wait. Sure enough, Bubba Hatfield, your neighborhood transplant from the land of dixie, gets him a hankering for some more boiled peanuts which, for some reason, they never have on the shelves in the local grocery store. He'd really rather buy some off the shelf at a local store, on account of how bad his craving is, but knowing there's some boiled peanuts on the way will help salve his itch a little, so he fires up his browser and finds him some of that bliss in a can. Now, what to his wondering eyes does he see? Under delivery options, there's a new 'IMMEDIATE DELIVERY' option for just $5. What? Are they going to use a rocket to send a can of boiled peanuts all the way from wherever the hell Amazon is all the way out here? He skeptically reads the 'more information' link about this new delivery option. All it says is they guarantee delivery in 30 minutes or less, or his peanuts are free. What the hell? Yeah, an extra $5 for a can of peanuts is ridiculous, but the thought of being able to eat some of those heavenly morsels within just a few minutes is too much. He selects IMMEDIATE DELIVERY and punches the buy button. The friendly Amazon truck, which just happens to have boiled peanuts among its cargo, adds Bubba's address to its current route. In 27 minutes, 30 seconds, an incredulous Mr. Hatfield is gazing, teary-eyed, at a can of purest dixie delight right there in his hands.
