A bit related.
Blackstone audio is the oldest and best audiobook publisher.
They have an appp called DOWNPOUR.
Their regular priced books are expensive.. 20s and 30s
However they have a daily sale book for 3.99 and two related books for 4.99. Those books tend to be older or classics.
Also many libraries have apps like CLOUD and among the dross one can find the more popular classics. Usually agatha christie and some of the other British and Americans. I just listened to 2 wila cathers recently.
