That's a lot of money to hand out once all is said and done. We had probably a hundred trick or treaters through here last year... fifty cents a piece... ouch.
I don't ever keep candy in the house, but I think Halloween is one of those cut-loose-and-go-with-the-flow days. Let them binge and have fun and enjoy it, and then secretly throw the rest away on November 2nd or 3rd :)
That being said, I guess stickers or little pocket games would be cute. Although, the big kids wouldn't really appreciate them. I know I always threw away anything that wasn't candy when I was a kid. And though I was NOT involved, the house that gave out fruit got egged every year.
