Clearer.io Address Validator

Shopify does not have a built in feature to exclude PO Boxes. If you only ship UPS this is a huge issue! I searched high and low on the interwebs looking for a solution and there was only 1: Address Validator. I installed it and needed some further customization so put in a feature request. This normally would have taken weeks, but somehow their support team resolved my issue within hours! We are now able to alert customers who checkout with PO Boxes and request a street address on the order confirmation page. The customer support responsiveness made this a pleasure to troubleshoot. Thank you!
