BookBub claims to offer "Great Deals on Bestselling Ebooks." And that's what it does. I get a daily email tailored to my reading preferences. Some of the books are new, some are older titles, some are by "name" authors -- mostly the older titles -- and a lot are by new (to me) authors. Prices range from $0 up to $5.99 or so. A lot of the $0 or $.99 books are parts of series, with other books in the series going for $2.99 - $6.99. Nothing wrong with that. $4.99 is as much as I spend on light fiction these days, so I check prices on other books in an author's series before taking that first taste.
