The next logical step is to use everyone's home as an impromptu fulfillment center.

Let's say Amazon has a full list of every possession you own and the price you're willing to sell it for. Any time someone goes to buy a thing, they find a nearby place that has it for the cheapest price, including shipping.

If you happen to win that round, they sending a shipping person^H^H^H^H^H^Hdrone copter into your home to pick up the item and transfer it to the buyer. They automatically credit your account the appropriate amount.
