You make your kid use her allowance to buy food at the grocery store for lunch?
Yes I do. I have since she was 16 years old. Her allowance amount is based on the cost of school lunches, an amount for entertainment, and an amount for saving for luxury items like the expensive jeans Mom won't pay for or iTunes cards. She can choose to buy lunch items at the grocery store and have extra money for entertainment/savings or she can save herself a little time and buy pre-made food. She is learning how to budget. She is very happy with the arrangement since several of her friends have to pay for their school lunches from their part time job paychecks. Her paycheck is hers to save or spend as she sees fit. Because we have always emphasized "saving up" from allowance even back when she just got $5 a week to blow, she's a pretty good budgeter and is saving most of her paycheck for college expenses. Except she did buy new snowboard equipment this year since she's working at a ski area and gets free skiing.
