Coming from as far as you are, I know the fear is getting to Norman without tickets assured. Your son will have a better time if you sit with the masses than in a club section, IMO.
I've never paid more than face value for any ticket in Norman. The only time I've paid more than face for any OU game was the CCG against Nebraska in Dallas in 2010, and almost every Texas ticket I've ever bought.
I almost always wait til game day. Now you have some decisions to make. You can get a pair for under face for sure, if you're willing to wait til 30 minutes before kickoff. But I like getting there in time to see the whole pregame. If I was coming that far, I want to see the special teams guys walking out onto an otherwise empty field 80 or 90 minutes before kickoff. Depends on the game.
West Virginia is late enough in the season that you might find some tickets for well below face value if the weather is a challenge. And obviously, tickets in section 5 are going to go for more than those in section 38. But you're not going to know kickoff time until the second week of November at the earliest. If the game is at night, then sun location doesn't matter. That late, it might not anyway.
But whatever the seat, you're going to pay more for a ticket 90 minutes before kickoff than you will 30 minutes prior. Unless OU goes undefeated and West Virginia is contending for a spot in the CCG, you will be guaranteed a pair for below face value 30 minutes before kickoff. Most likely an hour, which gets you in for most of pre-game.
I've paid less than 200 the last two times I bought Texas tickets. You sure don't have to pay that for a West Virginia ticket in Norman. Try to get to the stadium area at least two hours before kickoff, to get a decent parking place and pursue your tickets. The closer to the stadium, the less expensive the tickets available.
Good luck. And if you post on the two OU sites that have ticket boards what you're doing, you'll likely have some face offers early. Some sellers avoid that, because scalpers say that stuff all the time. But most Sooner fans, if they have season tickets but can't make that day for whatever reason, would love to sell their tickets to you. Most just want face back, and avoid the hassles.
Good luck.
