If the thought of carrying coupons on your cell phone seems enticing, you'll be glad to know that Cellfire (a free app that lets you redeem coupons via your mobile) is now available on any phone with Internet access (it was initially rolled out for Cingular users only). Just log onto the site to create an account and when you want to redeem a discount, all you have to do is show the cashier your digital coupon. We tried it with our smartphone and after punching in our NYC zip code managed to find a modest number of deals. The actual process is a little weird (especially if you're used to handing in coupons), but otherwise it's simple. Our only nitpick is that we wish there were more participating retailers. Click through for a look at the actual coupon.
