Cellfire mobile coupons save a buck

Cellfire is smart. The free mobile coupons company knows three things it needs to entice users to use its digital chits instead of stuffing paper cutouts into wallets, purses, and pockets.

1. Provide multiple ways to get the product. Cellfire is a downloadable PC-to-mobile app for BlackBerry, Symbian, and Windows Mobile, but it also offloads into the phone via WAP (point browsers to www.cellfire.com/) and through some carrier agreements.

2. Offer compelling brands. In addition to dozens of national chains, like TGIF and 1.800.Flowers, Cellfire's service gets local, offering discounts for hundreds of neighborhood merchants and regional chains in metro areas to total 10,000 merchant partners across the U.S.

3. Make coupons easy to redeem. The coupon for San Francisco's North Beach Pizza gave me two ways to collect savings. I could select "in-store" to get a coupon code to flash the cashier, or click to call the vendor and read back the code. I could also clearly see how many more offers I could collect and (2) how many more days I had before each coupon expired (5).

Cellfire's coupons update every two weeks. Although the service itself is free, users will get slapped with the cell phone carrier's data charges. Better stick with those paper coupons if you don't have a data plan.
