It just depends on what you want. Ticketmaster is fine as long as you know that you will probably end up getting upper deck corner seats. If you are looking for something close to the field or just having lower level seats, you will have to go to either NFL Ticket Exchange, Ebay, etc. Obviously, you will pay a premium for the lower level seats. Plus, high demand games (ie, home opener, Steelers game, etc) will be more expensive than a game in December. Hope this helps.....
