title: Clearing purchases from iOS in-app purchase sandbox for a test user
body: <p>Does anyone have any ideas on how to reset and/or clear the iOS in-app purchase sandbox?</p>
  
  <p>I have an app that I'm testing with the sandbox, and I'd like to test new purchases without having to create a new test user every time I purchase something.</p>
  
  <p>If I don't do this, then I (of course) always get a message that the in-app purchase item has already been purchased when I click on my app's buy button.</p>
