title: Titanium Ti.Storekit on iTunes store: purchase works fine, but how do I 'consume' the product so it can be purchased again
body: <p>I have the Ti.Storekit working nicely in the sandbox. Purchase works fine just as in the example code.</p>
  
  <p>When I try to purchase an item a second time (say 1 ream of paper) the store says I already own it and refuses to sell me another.</p>
  
  <p>How can I 'consume' this product to allow me to buy again?</p>
