Football Season Tickets are the best option
I've seen a bunch of people complaining that Wisconsin, Miami, and MSU already sold out in the lottery process.
The current secondary market prices are the following on SeatGeek:
Wisconsin - $577
MSU - $200
Miami - $440
Total- $1,217
The cheapest ND Football season ticket is $1,175. You could have bought season tickets for that price you'd have to pay for those 3 games alone. PLUS you can get priority to buy additional tickets for every home game plus the Shamrock Series PLUS you get priority to buy postseason tickets over all other donors/Alumni. The best move I made is just to buy season tickets and I can go to every game while buying extras for the games I need. They're still available even though the Miami and MSU games are sold out. You can even pay over time through their payment plans. It's a no brainer really.
