Clearer.io Address Validator

Early days for us with the app but the initial indications suggest it has been a good addition for us.
We have had a number of issues with EU customers getting confused with address formatting in our Shopify checkout and this has resulted in carrier returns.
We have also been able to block pack station delivery addresses which has been helpful.
So far so good.
The guys at Roboturk were very helpful in guiding us through the initial set up.
