Fiction Hardbacks: Never = No lost sales here.
Trade Paper Fiction: 1 or 2 per year = You are not making much money off of me

Mass Market Fiction: Used to be 5 or 6 per month, before the price broke the $5 mark, now it is 1 or 2 = Losing sales
In the last 2 decades, many of my local book stores have closed and or their stocked selection became limited. Future Fantasy, Tower Books, Crown, Little Professor.... RIP
Now I have the Biggies, only B and N and Borders. I left off Costco, Walmart and Target as the do not offer selection, only High volume title choices.
e-book: Back to 5 or 6 titles (Webscriptions) ,(and I have stopped spending money on more shelving or Storage crates)

Public Library: Is my source for reading books that are only available in HB = Gee, 1 sale per dozen readings or more.
To me,
Publishing is
making a book presentable to the reader.
Do that jobwell, whether it be for paper or e-books .
Price and Availability still rule my purchases.
