I'm trying to create a custom message appear for certain products that are flagged as so from the admin panel. These products will create a message on both the checkout and product page. For example some products will have to give an alert saying "This product does not give free shipping." in a red box.
I've attempted to create a module for this with an event handler however I can't seem to figure it out.
Can anyone point me in the right direction as to how to solve this issue?
