Clearer.io Address Validator

This is a wonderful app and it helped us in so many ways. It helps us not to get PO boxes to ship to as we don't use the US postal service for shipping. When we were not shipping to other countries it gave a much more clear note to the customer about what to do to get in order to their country. Shopify's note to the customer is simply, "Cannot be shipped". The app also puts figuring out a proper address on the customer without being difficult. Otherwise. we'd have to call the customer every single time and try to get that figured out together. It has so many other features that you don't realize you need so if given the opportunity you should at least try it for a couple of days to understand what you're missing.
