Rex Specs review for Clearer.io Address Validator

We were having several address changes a week and multiple "return to senders" a week before getting this app. Now that everyone auto-populates addresses and clicks "buy" as fast as they can this has changed the game for us. It makes people *think* for a second before entering an old or incorrect address. In the week since this was installed we haven't had a single address change post order! We're hoping the same is true for "return to sender" items be this may take a bit longer. Our first impressions with this app are great once its up and running. This will free up customer service reps to take care of more important issues. A small price to pay once you factor in re-shipping costs, warehouse packing fees, and emails and calls for address changes/"lost" packages.
