Hi Sarah, you can try www.nfl.com/tickets or www.ticketmaster.com/nfl or www.stubhub.com have fun! :)
I would go to www.nfl.com/tickets How have you been Sarah? ~jeni :)
Or, go to the NY Jets or NY Giants website, you should be able to buy tickets right from there, I think?? Have never been to a pro game, only pre season & the tickets were given to me. Let us know what you end up getting!
Did you find the tickets Sarah?
