Does anybody have any experience or knowledge of getting books selected for Book Bub? I'm interested in submitting one book that's currently in KDP select, but when I look at their criteria I see that they're more likely to select books in wide distribution. But if I take the book out of KDP select, the lowest I'd be able to go on price is 99 cents, while if I kept it in I could make it free. (I'm trying to use the first book as a lure to get people to read the second book in the series, so I'm not too worried about price). So - is it more likely to be selected for a Book Bub promotion if it's free at one source, or if it's 99 cents at many sources? Anyone know?
