Halloween will be here soon. Today is October 14, 2018. Here’s the idea. For each trick or treater, be sure to give them a piece of candy, which of course they expect (or something healthy if you can do that) and also give them the Halloween trick for parents. Tell them that’s what it is and say they should give it to their parents. Some will.
Print this flyer on bright orange paper.
Feel free to customize this for your state or other websites you want to put under references.
What else? You could add your name and phone number. Last year I had mine on the flyer and gave out about 65 flyers and did not receive a single phone call.
Anyway good luck with this.
