That's the first thing I looked for because my little guy threw a tantrum tonight
while unloading groceries and threw away an entire gallon of milk. That is coming out of his allowance for sure. He only gets his allowance once a month, so I need to keep track so he will know how much he gets. I can't figure out how to track it with points without messing up the other stuff. I let him choose what each chore was worth, so when I issue demerits they are high as well.
