Couldnt see this posted anywhere and I have not dissected every post to see if its has been mentioned yet.
SOE President only released the info a hour ago and normally these promotions are not announced.
Sony have moved this promotion to Sunday 4th November in the USA.
Station Cash can be used in many of Sony's games like DCUO and Planetside 2.
This promotion gives you three times the value for your dollar, the best time to buy.

I've posted here because it is not active yet but it might help someone who was about to make a purchase.
