This isn't on sale, but wow, do I consdier it a wonderful deal. If you like Sherock Holmes, then this is for you. All of his stories, over 70 hours worth, for only one credit at Audible. In my case, that credit only cost $0.99 from one of the last specials, but for this, I think it's even worth a full cost credit.
