The premise is pretty simple -- pop over to perks.nokia.com (currently offline), browse for deals and coupons, and click save on any you care to cash in. The discounts you pick are automatically sent to your phone and, just like Groupon, all you need to do is show the barcode to the register jockey. As a nice added touch, Perks also pops up directions to the store in the mapping app. For those who prefer motion visuals, a vid's hosted up after the break. [Source: engadget.com]
