Question for you young bloods who know about station cash

[Dov]

ALCON,

I never used station cash before while I've been subbing for PS. Now, I've looked into the station cash system enough to see SOE does sales and bonuses every once and awhile. So the question - for those familiar, what's the most effective way to buy station cash. I saw you can get an extra 500 with a 1500 ($15) card from walmart. How often does SOE do double or triple sales? Do "pro's" buy walmart cards and wait till a special SOE bonus offer?

Thanks - eager to start stocking up.
