Cellfire, a San Jose, Calif.-based company, said today it has launched its mobile coupon service in Seattle.

Cellfire said more than 80 Seattle-area merchants are issuing discounts and coupons to those who sign up for the service. Restaurants such as Alfy's, Round Table Pizza and Cold Stone Creamery are participating, as are other retailers such as Hollywood Video.

Moving the coupon business to mobile phones is one more step toward mobile shopping. I wrote a story last month about how there is an increasing amount of buzz around that phenomenon and how various players are testing a lot of intermediary steps before it becomes a very big market.

With Cellfire, consumers can access mobile coupons on their phone and redeem them by showing them to a clerk at the point of purchase.

The company said it supports more than 600 different mobile handsets -- I was even able to log in to my 5-year old Sanyo.

You can sign up by going to cellfire.com, or texting "WA" to the shortcode 22888.
