While the Free titles for Now Members facet shows which books are free, it's not easy to tell from a product page if a book is free or not (once you already got a free book for the month).
Adding some type of free book notice (e.g., icon) on the product pages would have benefits for LN members as well as non-members.
- It could serve as an incentive for a non-LN member to sign up for LN, when they see that they'd get the book they're viewing for free.
- It would help customers (who already got a free book for the month) to discover other free books they can add to their "LN Freebies" wishlist while generally searching the store for certain topics or types of books.
- It would spare customers who come across a book from inadvertently buying a free one they could have chosen next month, assuming they didn't need access to the book immediately.
Thanks for your consideration!
