    Seems to be basing the savings on the print copy, not the kindle version. Print copy is listed at $9.85 on Amazon for me. Which, of course, is immaterial due to the fact that the only free version is Kindle…

  Might need to be a bit mental for that 4.25 error.

  No seriously, it's 6.91 on Au, so probably just an amazon glitch.

  123 pages and 2 5 star reviews.

  Can't go wrong when it's free.
