title: Change the price of Android application?
body: <p>I'm planning to upload my Android application on Google Play soon.
  And I heard that change the Charge-mode to Free-mode is able to do, but the reverse is impossible due to Google's policy. </p>
  
  <p>And I'm wondering two things.</p>
  
  <p><strong>1. Then is it possible to change it from Charge-mode to Free-mode for a limited time(maybe 1-week or something), and then change it back to Charge mode, is this possible???</strong></p>
  
  <p><strong>2. Is it possible to discount my application's price from $2(US) to $1(US) for a limited time as well???</strong></p>
  
  <p>Please let me know!</p>
