Excellent product and excellent support. Many of our customers use freight-forwarding service and will forget to enter their Suite numbers in shipping addres causing the orders to fail, be sent back. Result is no sale and loss of initial shipping charge. No longer have this problem thats to King checkout

The app itself is feature-rich and has been very helpful for managing shipping restrictions and preventing problematic orders. It's easy to use, flexible, and backed by a team that truly cares about its users.

Support was responsive and quickly implemented support for validating a new early access Shopify field to collect a required ID number in certain countries. Really appreciate the fast turnaround.

Exactly what we we're looking for, since we can't use the checkout blocks as we're not on Shopify Plus.
