Monster Cart Upsell+Free Gift

I have reached out two separate times through the online chat inside the app and both times I received excellent service. They listened to the kind of campaign I needed and built it for me when I was struggling, and now are there for assistance when I get stuck. It gives me great confidence in using the app. Plus, it's the only one of about 7 free gift apps in Shopify that I tried that did exactly what I wanted it to do.
