The promotion isn't limited to C++. You'll also find books and videos on Java, Python, Ruby, and C#, including several from my Effective Software Development Series. If you're a programmer, you're sure to find something you can use.
To initiate your shopping spree, click here, and don't forget to use the discount code EPSALE at checkout. No, I don't get a kickback (other than my usual book royalties).
The promotion runs until May 18.
