The Simple Dollar, a website dedicated to helping people struggling with debt and bad spending habits, gave $100 to eight folks of different ages and incomes to see what made it onto their grocery lists. People with families and strict budgets did an incredible job of maximizing every penny, while the young and single tossed dollar bills at items like $62 bottles of wine and nearly $50 worth of frozen pizza products. Say what you will, but Totino's pizza rolls are an important part of your college diet.
