HA Product Options Variants

Was looking for an app that could add an additional fee to a product if the customer wanted an add on feature. After installing the app, I set up the settings for the product I wanted. However, I ran into the issue with the theme integration. After following the manual integration, I found that my theme didn't have the same codes that where needed in order to get the app fully up and running. I contacted customer support who where nice and professional in their work. My ticket did need to be given to a developer to work on, but that even got resolved fast.
