VidFall.com is an auction website for goods, services, and travel where prices fall because users are watching sponsored videos. We draw a group of users together to watch sponsored videos, take the money advertisers pay us for showing those videos, and apply the funds toward discounting a single retail item. The price falls and falls as more users watch videos, until eventually, there is one person who judges the price to be low enough and decides to click “Buy Now”. This user receives the entire group discount. Here is a one-minute video explanation: http://vimeo.com/84588387.
