As the kiddos head back to school, parents should mark their calendars to save some money during this year's tax-free weekend.

Between Aug. 11 and Aug. 13, most clothing, school supplies, shoes, and backpacks under $100 will be sales tax exempt, according to the Texas Comptroller's Office. That means shoppers can save about $8 for every $100 they spend.
