Just in time for the holidays, BOP and Tiger Beat are giving you a chance to win a free postcard from Selena Gomez‘s new favorite app, Postcard on the Run. Here’s how the app works: You can take a picture of anything on your phone and upload it via the app and then Postcard on the Run will send a REAL LIFE, physical postcard of your picture to the person of your choice (we’re talking old school snail mail straight from your phone – how retro-cool is that?). Like we said, Selena LOVES this app, so you’ll be sending cards the same way Sel does to her friends and fam!

How do you enter? It’s easy, just head over to our Twitter and follow @bopandtigerbeat. Then, tweet us a message about who you would send a Postcard on the Run card to and why and be sure to tag it #TBPostcardRun. The first 100 followers to tweet using the tag will get a DM with a promo code for a free Postcard on the Run postcard (PLUS one free scent so your card can even SMELL like the holidays). We can’t DM you if you’re not following us, so make SURE you follow us before entering the contest! If you have any questions about how to use the app, just tweet @postcarding.

The Postcard on the Run app is available for iPhone/iTouch and Android phones and you can download it from www.postcardontherun.com! Postcard on the Run allows you to instantly create and mail high-quality, custom postcards directly from your phone to anywhere in the world. No stamps or mailboxes needed! Personalize your postcard with a signature, mini map and up to 11 different scents for a fun twist!
