-Parking $5.
-N.E.R.D. CD $12
-Attending a concert and getting autographs and "restricted" handshakes from the group- I would say around $257.67 but for the sake of this joke lets just say priceless.
Now i've been a fan for awhile now and havent heard anything on their new CD since the day of the concert, and i must say-awesome. That and it was my first official concert. Decide for yourself.
