I'm incredibly disturbed and upset by the intensely aggressive replies to my question. Perhaps I worded it wrong.
I was trying to ask how to market to an audience who don't make buying choices for themselves and how to offer free copies to those readers.
If the answer is that I need to target parents that is all that was needed to be said.
I was really eager for helpful advice - I've clearly received an answer to my question and I'm grateful for that but I'm really upset by the rudeness.
