Maybe someone posted this already in the thread. Please forgive me if I'm repeating.
I've noticed that Amazon is trying to compensate for the delays by deeply discounting the price if you purchase a delayed book as a pre-order. I paid $7.20 for
Under the Dome as a pre-order and I see
Impact is now $8.87 and will probably drop lower as the King book did. This may work for me as Amazon will automatically drop the price if they go lower.
