title: Choose Woocommerce shipping method before address entry with postcode restriction
body: <p>I am restricting delivery methods based on some UK postcodes on Woocommerce, but that means the delivery options are disabled until an address is entered. The message that is displayed is:</p>
  
  <p><strong>There are no shipping methods available. Please double check your address, or contact us if you need any help.</strong></p>
  
  <p>Once an accepted postcode is entered only then a selection appears with choice of shipping methods.</p>
  
  <p>Is there a way to show shipping methods without entering any address and use the postcode restriction at the same time.
  I can't find any settings to overcome this.</p>
