I did some research and came up with these numbers. In most cases I found the exact same items (i.e brand, amount, etc.) but in other cases I found a similar product and adjusted the price for the amount. At the bottom you can see the price changes for items at the ballpark. Remember, these ticket prices are for tickets at the Coliseum.
