Arigato Automation

We've just started using this app a few days ago and have already found several ways for it to handle tasks that were impossible out of the box with Shopify or took a long time to complete. Best app we've seen in a long time!
Support is fast and very helpful.
Update: This app has been crucial in adding automations that keep our business running, notifying customers of back orders, notifying us of stock issues and correcting them, etc. Extremely flexible. If we could only keep 2 apps, we would keep this one (and Boxify to make up for Shopify's box dimension shortcomings).
