Beer Prices at Wrigley Field

Beer Prices at Wrigley Field... When I started vending way back in 2004 prices were 5.25! Can you believe that? Ah the good old days. All kidding aside, prices have increased a quarter every year. In 2005 they were $5.50, 2006@$5.75, 2007@$6.00, 2008@$6.25 and now in 2009 beer is $6.50. I know my fellow brethren won't like this but beers are a quarter cheaper in the concession stands but why would you want to walk and wait in line when you can be served upon :) It's all about the opportunity cost.
