FW member "henryrock" reported code D2F4 for a $100 bonus that you supposedly can get with Citibank PremierPass American Express Card. You can apply at http://signup.citicards.com.
The code is apparently valid, however no info about the bonus is displayed on the application page (it rarely is).
You can find info about this card at here
