Well, the jury is in and Amazon is not going to pay me for the paperback AMS says I sold. They say that someone must have clicked on it and then bought something else. While I'm happy for that someone else who ended up with the purchase, I think a click and a sale are two different things.
Anyway, only once in ten years have I won a "you're not paying me" case, so I have to just chalk this up to another loss. Sheesh!
