title: Good examples of UK postcode lookup flow
body: <p>I'm looking for a good, well designed flow of a UK postcode lookup process as part of registration for an eCommerce account.</p>
  
  <p>We're redesigning ours and want to see what is out there and how I can make it as friendly as possible.</p>
  
  <p>--Update--</p>
  
  <p>Basically our current design was a manual entry form (worked pretty well) which a less than experienced developer then bolted the postcode lookup onto.</p>
  
  <p>So the order currently reads: Country, Line1, Line2, Line3, Town, County, Postcode. And he just put a lookup button on the bottom of that. So user goes line by line, THEN looks at postcode and uses the lookup.</p>
  
  <p>I'd like to see some others in action because of the point made in the answers about allowing manual override.</p>
