Hi @Andreabarba ,
You can add a tag called "hide_price" and we'll implement the logic in the meantime!
Price should also be hidden from the collection.
I currently have a published theme (in this one, the cart and the price are hidden with the no cart template) but in a other theme that is not published, this is not reflected. I don´t know if I can´t apply this change because the theme is not published
Sorry for my rusty english, my native languaje is spanish
This is an accepted solution.
No worries for your English, it's great!
As for the template, yes you would need to publish the new theme for this to work correctly.
