We have a bunch of friends over and watch horror movies all night long. Each person brings a bag of candy so we have tons to give away to the kids. I also stock up over the season on some of the bigger candy like full-sized candy bars and some of the novelty stuff like stickers, pencils, light-sticks, and little toys to give away as well.
This year I got full-sized Ring Pops and Fun Dips. I saw the Ring Pops' cover and had to buy it.
And we also give away a prize for best costume. This year we have two; a Marshmallow Brain Burger for best costume under five years old, and an horribly awesome Transformer for five or over.
It's called Ejector and it transforms into a toaster!
