Feedback on Price Tempter

We just launched the first version of Price Tempter, an Amazon price tracking site targeted toward the lazy deal shopper. We tried to make every part of the experience easy including one click subscribe to an interest list, simple categorization of how temping a price is (i.e. you don't have to determine your price threshold), and integration with your existing wish list (coming soon). Would love any feedback you have.
