Titles by this publisher no longer have the notation "price set by publisher" and prices appear to have dropped. Many are priced not at the usual round numbers of $12.99 etc., but rather something like $11.67 or $10.94.
Fingers crossed that this mean what I hope it means
Edit: I just checked one book: American Sniper. It's priced at $10.94 on Amazon and $12.99 on B&N - first time there's been in a price difference from a major publisher in years!
