Christine and Justin are two NYC illustrators and run a web site called Wants For Sale. On this site they sell paintings of things they want for the exact retail price of the item. Once they sell their painting of the item they then use the proceeds to buy it. The things they want range from an order of buffalo wings ($12.70) to "financial security" (for one million dollars!).
