For those who aren't familiar with Cellfire, it's a service that provides users with an easy and less cluttered way of using coupons for groceries, restaurants, entertainment and more. The team have recently announced their submission to the Windows Phone Marketplace, we covered the app when it appeared on WinMob. Note that Cellfire is aimed at US residents only.

So if you enjoy saving money and wish to use coupons when you're out and about, let your WP7 handset do all the work for you. Clip the coupons to your grocer's savings card and away you go or simply show the sales person the coupon on your device. You can download Cellfire from the Marketplace for absolutely nothing at all.
