title: Android In-app Billing, multiple purchases of the same item
body: <p>Is there a way to buy a multiple of an <strong><em>item</em></strong> (SKU)?</p>
  
  <p>For example: I have an SKU named <strong>LifePoint</strong>, and i want to buy <strong>100 LifePoint</strong>. </p>
  
  <p>(in another word <strong>N</strong> * <strong>my_item</strong>).</p>
  
  <p>I found this <a href="https://stackoverflow.com/a/8660890/4224337">workaround</a>, but am looking for something better.</p>
  
  <p>PS: I'am using In-app Billing <em>Version 3</em>  and my item is <em>Unmanaged</em> (to buy my product many times).</p>
  
  <p>Thanks in advance!</p>
