If you are into deals then you most probably are familiar with Groupon, a deal-of-the-day website in major geographic markets worldwide. An official Groupon application for Windows Phone 7 has been released and is now available in the Marketplace.
The application features deals but unfortunately only in cities of U.S. and Canada — sorry international users, again. The application allows you to purchase on deals, accept Groupons, redeem them or find the closest one. The application is free and you can search for it in the Marketplace or follow the source link below.
