Great app for keeping checkout clean and error-free. It flags PO Box and zip mismatches instantly, which has reduced our delivery issues a lot. We also enjoy the freedom to reorder or hide any fields. Setup was fast, and everything works seamlessly with Shopify. Definitely a helpful upgrade for our store.
