"Here's an idea! What if you printed out a bunch of stickers with your friend code web address and stuck them on your candy that your family passes out for Halloween? THEN, not only are you giving kids some candy, but you're giving them the chance to make some crowns and give you some crowns in the process.
In other words, put that sucker on a sucker!"
Try it out! You never know. That might lead to some extra crowns for you and your family. :-)
