This app offers a lot of capability. The AIT team is very responsive and helpful when needing assistance.

This app is not only great in what it does, but the people behind are awesome! They are quick to respond to your inquiries and extremely helpful. Fast Simon has been by far the best app we use on Shopify. We highly recommend them.
