Ticket prices

Hey everyone! I know there’s probably a lot of people talking about getting tickets with their citi presale or whatever. My grandma said she’d pay for my rush tickets, because I’m in college with no job right now. She told me just to let her know how much I’ll need but I’m not 100% sure how much to tell her. For anyone who was lucky enough to score some good seats, how much did you pay? Thank you all!
