If you are looking for a large amount of GA tickets to purchase and do not want to buy them online or fight the line at the stadium, I recommend buying a booklet of 10 tickets. They are $85, so it's also cheaper per ticket than buying them individually. You can use the tickets for any game throughout the series. You can buy them at the HyVee (our Kroger) in Council Bluffs. Some other grocery stores carry them as well. This is what my family and I do every year. It's very useful if you're buying for a family or staying in Omaha for the week and don't want to worry about buying a ticket before every game.
