That's a really nice edition (Jardine actually rewrote the entire novel for the Author's Cut and gave an extensive foreword explaining why), which I picked up when it was a Canadian freebie during the summer.
Also free @
B&N UK &
Kobo UK. Likely also iTunes UK & Google Play UK, but they're under a slightly different version from the Canadian store so I can't easily pull up the links, sorry.
ETA: switched into the other user account to check something, and pulled up the
iTunes UK link for this, where it is indeed also free.
