November 30th - midnight Pacific (12/1 at 3 AM EST) is the deadline for the early payment discount of $5.
For full-priced teams, this is almost 10% off (OK, it's 9%).
Payment isn't due until Opening Day...this is just a chance to take care of it now and get it out of the way. See your current status at http://www.benchwarmerbaseball.net/useradmin/payment_summary.asp
No discount for packages or Orphan teams.
