If you're using it to catch up on other team's games then it's well worth getting for the year. I have re-watched Bills games using the "game in 40" section but can still do that using the weekly pass.
We're in London just for the day, 10am to 9pm I think. My Cowboy supporting mate and I. We're taking our sons for the first time this year. Are you going to one of the games?
