well not free free.. but..

for each can of food you bring, and for each cd you buy at good records you will get a hot chip ticket

so you now have a choice..
you could be a jerk and buy a 30 cent can of beans, and a 4 dollar ctr cd..
or you can be a nice person, and bring 4+ cans of beans, and purchase a cd..

either way your not payin for a 20 buck ticket that has an additional 8 dollar ticket master charge..

remember people are hungry, hot n miserable down south.. help'em out
