Whatever the rights and wrongs of ebook pricing, I will definitely take a chance on a new author (by which I mean new to me) if I can try the first book cheaply. I noticed that they seem to be selling first volumes of trilogies/series in the sale and then linking to the rest of the series at normal price. It seems to be a good strategy.
In other news, I have made progress today, but I am now feeling very tired. I'm sure I used to be able to get more than this done in a day. Getting old sucks. :(
