That information is incorrect. It depends which show you are going to whether you will need a code or not. Some shows will have presales right here through the fan site while others will be hosted by ticketmaster.
Ticketmaster presales, such as Southaven MS, will require the use of a presale password.
Mandy, did you pay for your membership or was it free?
you don't need a code if you are a fan club member - i think you just sign in and buy the tickets as being signed in
