Maybe you need to already own the Kindle version for that price to show? So I decided to test it out by getting the Kindle version from one of my libraries. Guess what it says now?
Regular Price :$33.07
Special Price :$3.95
Whispersync for Voice
You're halfway there. You already own the Kindle edition. Buy this audiobook to switch between listening and reading
Because you own the Kindle edition, get this audiobook for the reduced price of $3.95
Crazy, because I don't own the Kindle version. I'm only borrowing it from the library.
