Anyone on ticket watch?

I go to HHN every year but I haven’t actually tracked ticket prices. For some reason, I felt the urgency to buy early. I’m already booked for a one day reg ticket and one express for Sept 6th. I checked prices today and they’ve already jumped $20- $30 since I booked last week. It’s only July! I’m curious about how this will trend. I wonder if the Ozzy announcement had anything to do with it? Just a thought!
