IntelliJ IDEA 10 - 40% off personal licence
PyCharm 1.2 / PHPStorm 2 - 50% off personal licence
RubyMine 3 - 30% off personal licence
also YouTrack - 50% off any edition
I have been looking at PyCharm and PHPStorm so this offer has come at a good time for me.
I am looking to start some Java (Android) development and since the Java IDEA includes all the language plugins and is equivalent to PyCharm + PHPStorm + RubyMine + more all under the one roof I might consider the full IDEA with 40% off although the eventual upgrade cost will be more than upgrading just 2 of the language specific IDEs.
