Woke up to this from Amazon this morning. So I had to go in and reprice most of my authors books. I guess the cost of living of goods and services has finally hit Amazon. It only affects paperback books.

Changes to royalty rates for print books and color printing costs starting June 10, 2025

Starting June 10, 2025, we are changing the royalty rate for books priced below certain list prices (for example, less than 9.99 USD) from 60% to 50%. As a result, you’ll have books earning zero royalties after this change. To avoid this, you can update the list price for your affected print books. Separately, we are reducing color printing costs for paperbacks in some marketplaces. Learn more about royalty rate and printing cost changes.
