title: Android Play Store - How to offer free copies of paid app
body: <p>CONTEXT: I have a free and a paid version of an app on the play store. I would like to offer free copies of the paid version through post contests in various message boards
  (ie: I would post in X forum: MY APP - SALES PITCH - FIRST 5 POSTERS GET FREE COPY OF PAID VERSION!)</p>
  
  <p>Anyone know if (and how) this can be done?</p>
  
  <p>Thanks!</p>
