Beware of losing credits.
I’ve been with Audible for a while and had run out of things I wanted to listen to, so thought I’d have a break, re-listen to some old ones and then choose something new. You can only have max I think 6 credits and after that you keep paying every month but you get nothing for it. I was not impressed as I probably wasted half a years worth of subscriptions. No reason to do that except ripping people off.
