It is NEVER about the candy
Truth: It takes me for-ev-er to get through the grocery store. Same when I am at Target. I have to look at all of the packaging and critique it. Why that typeface? Why those colors? Why did this or that design catch my eye… and what do I like, or loathe, about it? What would make it better or why is it spot-on perfect?
When son would go shopping with me I would enlist his opinion about package design and get him involved in the conversation. He was only 7 but he got it and developed a dialog and awareness about how design effects our decision making. Our consumerism. (btw he is now 23 and is a brilliant vfx artist working in Los Angeles.)
