I'm a Cardinals season ticket holder and went to Super Bowl 43 in Tampa.
I didnt get drawn for tickets, so I had to buy them on the secondary market.
I used Craigslist. I found a season ticket holder who was drawn, but couldnt go. He wanted to make sure he sold them to another season ticket holder that wanted to go.
We met at a bank just down the street from my work to do the transaction. I first did some research into what REAL tickets looked like to avoid being scammed.
Face value for the tickets was $800. He sold them to me for $1300 a piece. This was actually a bargain compared to what tickets were going for at the time.
