Yeah, this was my issue with all I could find so far. It seems like 'working as designed'. Perhaps those who publish on audible would like to be able to opt in or out of various sales/credits etc but as a customer I prefer that I can get anything with a credit.
> Basically Audible splits the money spent on credits among the books that the credits were spent on, except weighted by the retail price
Is that all credits in the system (similar to how Spotify was weighting streaming subscriptions (to my understanding)), or per user. I would prefer the money from my credits to go to the books I purchase, not be weighted with purchases by all other users.
