I am a firm believer that out of all the ways to get creative at Halloween, the dispensing of candy should not be one of them. It’s a simple idea: kids come to your door dressed up, wanting candy. They don’t want minicomics, thrift store games, baseball cards, your Pokemon CCG commons, or the like. Nobody goes door-to-door saying “Trick or small-sized version of whatever you personally are interested in!”
Just make with the fun-sized Snickers and everyone will be happy.
