If you edit a Product, it will show you the master_categories_id at the top of the page:


The master_categories_id can be used as an identifier that a Product is a CD or Vinyl, if all CDs and Vinyls are in Categories that hold only CDs and/or Vinyls ...

This would allow a count on Products in the shopping_cart that match the master_categories_id numbers of CDs and Vinyls vs the total item count in the cart ...

The idea is, if the count of Products using these master_categories_id values matches the total items in the cart, then all Products are Media ... if not, then the whole cart is not Media ...
Amazing. Thank you.

So I guess I have to add a code to the PHP file that would allow the check out to ONLY use media mail for the selected Master ID Categories?
