Cellfire is a cool new service that allows you to save money wherever you are. It offers coupon deals for restaurants and stores that you use from your cell phone -- which is nice since you always have your cell phone with you. Their service works with the iPhone, RAZR, Blackberries, Nokia phones, and Windows Mobile based phones. The coupons get downloaded to your phone, you select the one you want to use, show it to the clerk and you get instant savings.
