According to the e-mail I got, the only books that can be purchased with this code are
here. It is possible it may work on other titles beside these but I don't know. Anyway, the code is 25%off and it expires October 31. I used it to get
The Accidental Billionaires: The Founding Of Facebook: A Tale Of Sex, Money, Genius And Betrayal for $6.97 instead of $9.29 (which was already discounted from the $15.95 list).
