I checked available tickets about 10 minutes prior to kickoff, on both TM and SeatGeek, and there was one in 134 Row 15ish for like $300. Other than that, still way overpriced.
Nope, no one selling in person outside the gates anymore.
I’d say it’s unlikely to find tickets for $100 each (even in the 300s) unless you wait til riiiiiight before kickoff or even shortly after.
