First link tells me "this item is not available for purchase". From that page I search for the book's title and find the same thing (same product page, with same reviews, etc.) But with a 13.53$ price tag. Infuriating to realise that the price you get is based on who you are somehow.

For statistic purpose, I have it at 8.8$ on .com from France (but in a french Caribbean island, so sometimes IP locations are messed up)

Price at the US link is $13.99. Australia link says they won't sell me the Kindle version.
