Sendtiment is a popular, easy-to-use greeting card app for Windows Phone 8. The app has over one hundred greeting cards in the free version and an additional four hundred plus cards in a paid variant of the app. The developer behind Sendtiment has just kicked off a 'Lucky Selfie' contest to celebrate Saint Paddy's Day, which will see one lucky winner bagging a $50 Xbox gift card.

It's really easy to get involved. All you need to do is take a selfie with something green (be it a shirt, mug, scarf, hoodie, dog or even a sticker). The only downside is this contest is hosted on Facebook. That said, with Titanfall just around the corner, a $50 Xbox gift card could be put to good use.

The contest ends on March 17th at 10pm (EST). Head on over to Facebook to take part. Remember that you have to reside on planet Earth to participate. Check out the contest rules for more information. Download the Sendtiment apps from the Windows Phone Store too:
