The annual Texas tax-free weekend returns Friday, giving shoppers a short window to buy qualifying back-to-school materials without paying sales tax.

From Aug. 7 through midnight on Sunday, Aug. 9, parents can enjoy saving on taxes on purchases of most clothing, footwear, school supplies and backpacks (sold for less than $100), according to the Texas Comptroller's Office.

Items can be purchased from a Texas store or an online seller doing business in Texas and still qualify for the tax-free weekend.
