I would like a list.

1. It has to be part of the theme (mall)
2. Better if it's a team prize.
3. It's a prize for the scavenger hunt
4. Don't make the other team feel bad.
5. No food
6. They're 13 year old girls.

Bonus Question: I am thinking of giving the people a list and a "shopping bag" for the scavenger hunt. They write answers to questions (like what's the third letter of the only baby store in the mall) on the list, but they put things (like a spoon and napkin) in the bag. Are there any better ideas?
