This is already happening in China. Because of the nature of shipping companies here it's not unusual to buy a product (typically off of http://taobao.com ) and get it later that day or the next day. Many of these businesses are based in Shanghai and if you live there delivery happens nearly instantly. One online shop, http://cheers-in.com/ delivers cold beer in Shanghai in 1 - 2 hours from an order. Stuff like this…
Great for consumers like us, but terrible for all of the people who work ridiculous hours under constant stress on warehouse floors or do deliveries day in and day out. I try to buy from brick & mortar shops purely because running a shop is a job that has a shred of dignity left in it.
