But to tell the truth, it there was a nifty prize inside or a had-to-have-it send-away, I would pester my parents for anything. I really disliked Fruit Loops and Apple Jacks, but I recall whining for boxes of each because I wanted the prize inside.
I still have a small collection of cereal toys, too.
