Dynamically change address fields for international orders. Fail b/c they try to adapt to US format
Our international orders fail often because of AVS mismatch. Usually it is because they put something into the Zip/Postal code field even though their country doesn't have Zip or Postal codes.
If the form could dynamically change when Countries are selected in the drop down box, that would be a huge help. All you'd have to do is remove the Zip field.
And if you'd really be awesome, you should have a link to a pop-up that helps them format their address.
