i am going to the JB concert on July 17th and it would mean the world to me if i got the chance to meet them!! i have heard that there is a contest to win them but it seems impossible. Also, how much does it cost? Do i need to buy an item that they sell (like a t-shirt or cd etc.) to get in? please help me!!! it would mean so much to me.

Thanks for all your help :]
