The Couple Challenge Book review for Clearer.io Address Validator

Not effective if the pop up only appears on the thank you page, we still have to check all the addresses manually and there are still address errors or missing house numbers etc. The addresses that this app corrects only consisted of changing from lower case to upper case and nothing more and we have to pay money for that?! If the pop up would have appeared in the checkout it might have been a different matter, but that's only available for plus merchants!
