This is a yahoo link and on the page it has four ticket outlets like stubhub. I bought three tickets for the Viking preseason game from ticket liquidator. They ran about $84 each and I'm on the 100 level. I wanted to go during the regular season but work made it tough to fly cross country, plus the other two I was going with couldn't go then.
I was really looking into the Saint game tickets starting at $165. There are fees and there might be sales tax...
You can also look up the Charger tickets on these links.
