Rach's Reading Club

Oh, I wasn't planning on listening to the crossover books. Those are crosses with some of her other universes. But she has The Wicked Witches of the Midwest Mystery Series that I apparently decided to buy at some point.

I originally had planned to not buy a series without having listened to the 1st one 1st. But then some books will be on sale when I've already bought the 1st one, so shouldn't I buy later ones while they are cheaper? Then there is the fear that the other books will be removed from Audible, as has happened in the past. I don't want to lose the rest of the series, so I sometimes buy it because once I buy it, I don't lose it if it leaves. But then I end up in a situation like this with a bunch of books I don't want because I didn't listen to the 1st one before buying the others.
