Sell Advert nodes - copying Product Display fields to new entity node
I have a product type called "Ad top". Two custom fields: Duration (taxonomy term: 1,3,6,9,12 months) and Pages (Taxonomy term: Homepage, Other pages).
I created 10 products of the Ad top to cover all variations of Duration and Pages, each product has different price.
Then I created a Product Display: "Top Ad" with reference to all 10 products. When I view it I have two Dropdowns: Duration and Pages. depending on the dropdowns price changes as expected.
