When are they charging for those paying full? Don't really care about calling to process it early but it seems weird that they're doing it this way. No processing email from them since the one went sent a while ago.
If you didn't do early processing I don't believe anyone can give you a firm answer on a charge date yet. It appears SSC is only charging those who opted for early processing at this time, so I'd guesstimate from this week Mon 13 to the end of the month.
