I have a product, a book, I have both the paper version and the pdf version.
I want to sell the product in both versions.
I created a "version" attribute and created a configurable product which has two children "pdf version" and "paper version" , Magento automatically created two virtual products.
Magento shows the product as unavailable in the catalog.
The paper version should have its quantity while the pdf version has no quantity.
How can I create a product that, based on the version, has its availability and quantity?
what is the best way to do it?
