My kids did this at ages 9/11/13. When my husbands paycheck went from 2times a month to once a month, I warned the kids that I could buy X number of snack and easy foods. When they were gone, there was no money till the next month. Everything I bought was gone in four days, and they complained. There was no money for new groceries. The next month amazingly the food lasted thru most of the month. They were then very careful to make it last.
