I've been a Butterfinger fan since I was kid. When my parents would leave me at home from time to time, they would leave me a package of 5 mini pizzas, a package of butterfingers and six pack of mountain dew...
So usually for halloween, I tend to buy and hand out butterfingers, snickers and reeces cups. If I have leftovers, then I have an ample stash with me during my winter hunting trips.
It's been so long since I've had kids to take Trick or Treating that I honestly can't remember. However, I gave out Snickers this year because I know that between the wife and I, any leftovers, while not going to waste, will definitely go to waist (and hips and thighs...). Also, I gave out coupons for a free download of Plants vs. Zombies. It was a promotion called "Stop Zombie Mouth" run by Electronic Arts' Pop Cap division and the American Dental Association. They were as popular as the candy!
