PriceDropAlert. Hmm interesting idea, no? You can see this extending to all sorts of places (mobile phones p’raps?). Although it goes against the ‘instant gratification’ vibe a bit.
Price Drop Alert enables you to add products to your Price Drop Alert list. You will get an email whenever your selected products are available at a cheaper price…There are more then 6 million products from over 500 top merchants in our participating web sites.
