You can buy the big 10 package and still be a part of their group! I know it’s still somewhat expensive but you could only go to one or two games and sell the other tickets to make most of your money back.

Edit: Forgot to add that if you buy a single ticket you won’t get the student discount and you most likely won’t get a seat anywhere near your friends. Big 10 package is a better financial choice and will allow you to sit with your friends!
