"Mountain View wants you to know that Google Offers isn't another Groupon copycat; that's why the service is now taking a different approach. Whereas you've previously had to pay for discount vouchers in advance, you can now clip them for free and then pay for purchases in-store, making Offers more convenient to use. The company's also introducing coupons outside the main Offers app, adding them to Wallet, Maps and Search, as well as programming Google Now to flash a notification whenever you pass by a participating establishment. Here's some even better news for veteran users, though: you can either get a refund for unused offers you've paid for, or get your money back as Google Play credit. If you go the latter route, you'll get extra dollars on top -- enough to jazz up your phone with SwiftKey or Photoshop Touch."^^<http://www.w3.org/2001/XMLSchema#string>
