title: How do I get the estimate shipping zipcode in Magento?
body: <p>I am writing a custom shipping rates module, and I can’t seem to figure out how to get the estimate shipping zipcode… I know how to get the zipcode once the order has been created, but not for the estimate shipping portion of the checkout process</p>
  
  <p>Any input is greatly appreciated!</p>
