How Valuable is Station Cash?

[Tooterfish]

So there's a sweet deal going on today, offering 3x bonus to station cash purchases. I'm seriously considering the $100 dollars for 30k option (normally $300). I haven't seen any catalogs for Planetside 2 items yet, however, or really followed the micro-transaction talk much. Does anyone know how Planetside is specifically going to utilize the station cash, and if 34k in station cash is/isn't overkill?
