Do-it-yourself lunches: Save cash by brown-bagging a great sandwich

You can save a bundle of dough by brown-bagging a sandwich for lunch. Consider this: By plunking down $5 to $7 on a noontime meal five days a week, you’re spending $1,300 to $1,820 a year. That cash could buy you a well-deserved vacation, or the smaller clothes you’ll need after skipping the french fries that come with a restaurant meal.
