Seems like premature publicity. Great idea that is far from being useful right now. If you actually want customers you need to prove you can provide value.
My first try was "iPhone 4" and it showed me the average price for all iPhones, from iPhone originals to broken iPhones to locked iPhones etc. That's useless. unless you can identify the specific product and give me a number, this is not useful and I'm better off googling it
