For families like the Stratton family, back to school puts a dent in their budget.
Marissa Stratton has four children, three of them school age. Last year she estimates she spent $400 just on back to school needs.

From 50 cent erasers, pencil sharpeners and glue sticks to 97 cent Crayola markers, Walmart and Target got serious this year about earning your back to school dollars.
