FabGadget: Coupon Notifier
If you're using Firefox for your internet browsing (and you know you should be), there's an add-on extension that is just shy of ingenious. Coupon Notifier sits in your statusbar while you're browsing -- and if the site you're visiting has coupons available, the Notifier tells you discreetly via a cute little symbol. You can then peruse and/or download the coupon right there. How friggin' sweet is that?
