The blog's broker has them cheaper than directly from the UGA, but if you're looking to save even more money then it's probably wise to wait until closer to December 30th.
Right now UGA has two ticket prices - $85 regular and $125 for club. If you ordered as a Hartman Donor your order is being processed and sounds like tickets will be mailed next week. If you're in the group that is looking for something today, Ticket Monster's start at $78. If you're in the group that is waiting, pull up a chair. It might be awhile before they fall to reasonable levels.
