I'll start this by noting that plenty of tickets are still available (um, lol?) through Penn State and are located in the upper and lower decks of the north end zone for $70 each. I called and confirmed that as of 2:30 p.m. Monday.
Otherwise, same rules apply here as for the Alabama game. Don't try to gouge your fellow fans (see above, face value tickets are available), and be clear about what you're looking for and what you're trying to get rid of. Include your contact information in the post if it's not in your SB Nation profile. Thanks.
