If you're in the US you might want to head down to your nearest Microsoft Store. Why? Well in addition to all of the goodies you could pick up in return for handing over a little cash, there's also a chance that you could walk away with a free Windows Phone.
Announced on the Microsoft Store Facebook page, the giveaway is part of Microsoft's Opportunity Rings Instant Win game: "Come into a Microsoft store on May 3rd and 4th for a chance to win a free Windows Phone! We are giving away 8 phones per day, per store through the Opportunity Rings Instant Win game. Available in all US stores -- full-line and specialty."
The in-store giveaways will be taking place in all of the company's retail stores on this the first weekend of May. Over the two days you have 16 chances to bag yourself a new phone in each store, so we wish you the best of luck!
Thanks to Alan for the tip!
