Bless you for sharing. This worked for me on Dawn 2.0 as well!

That's too bad. The plus plan is way out of my price range. 

Thanks for the reply getxgo. This code works but it shows up in the cart. Some shoppers don't open their cart and go straight to checkout.  I need it to show in the checkout page where customers type their contact info. Is this possible? 

Thanks for the info. Unfortunately my templates only include cart.json.There's no cart.liquid on the list. This is a 2.0 theme.

I need to add a "note to seller" section in my checkout. I'm using the Dawn 2.0 theme and haven't found any solution for doing this in the discussions.
