Many of Addison-Wesley's recent C++ titles are introductory, and it's been so long since I was in need of that kind of book, I don't offer recommendations on them, though certainly many of the horses in the Addison-Wesley stable have excellent reputations. One book I have looked at and strongly recommend is Nicolai M. Josuttis' updated-for-C++11 second edition of The C++ Standard Library. Getting 30% or 40% off that book (or book+PDF combo) would certainly be nice. And frankly, if you don't yet own a copy of C++ Templates: The Complete Guide (by Nicolai M. Josuttis (who at this point should be sending me kickbacks--but, alas, isn't) and David Vandevoorde), this would be a good time to fill that hole in your library.
Happy shopping, and good luck with the drawing to win the combined bits of my books. I hope it goes without saying that you don't need to buy anything to get a chance to win the digital versions of my books, but in case it doesn't, you don't need to buy anything to get a chance to win the digital versions of my books. So sign up!
PS - My mole inside AW whispers, "We are advertising this promotion as applying only to C++ titles, but it works for any set of titles from InformIT." So if you want to scratch that Scala itch that's been bugging you or you want to combine your buying power with that of colleagues who use--gasp!--other languages, now's your chance.
