I've searced and found some places on the net in which you can buy or sell BSB concert tickets! Keep in mind that most of the sites listed here are broker sites. You won't find tickets for the normal price of $54.00 or less, but if you are desperate for tickets and are willing to pay, this is the page for you. Good Luck!
