My problem is that I am trying to sell a service and not a physical product. Subbly automatically makes one time purchases physical products so this means that it includes shipping and the ability to add more than one in your cart. So maybe they can add a separate one time purchase which I recommend being that there is only one option its not a very diverse selection. If they don't want more options and would rather keep it all in one then maybe they can add On or Off toggles for these options so that we will be able to make it more personalized. Regardless if you want to make it something anyone can do or not. Me and a buddy of mine own this business and we need this feature regardless or we are going to be forced to move to another platform. Please reach out Subbly team. Thank you!
