What if instead of doing that, you did an ornament exchange so that everyone brings an ornament under a set amount & you do the whole steal someone else's gift or get a new one thing. It's a lot of fun and you're not spending $30 on things that may or may not be loved. It's just a thought.
If you really want to do a giveaway, what about some chocolates, you could make some truffles & wrap them nicely. They're fairly easy to make & soooo tasty.
Have fun!
