Whoever wins the contest scores a fun-filled goody bag.
Consider making a big batch of one goody and then attending a cookie swap so you can get several varieties in exchange for your labor.
You can shop your local department store, Wal-mart, Target, Goody's, and so on.
Most big chain music stores such as Sam Goody are easily located through online sites.
Gather a goody bag, toss in a few trinkets and a sprinkling of candy, and you're good to go.
