BIRMINGHAM, Ala. — Shoppers in Alabama are picking up many back-to-school items tax-free through the weekend.

Retailers statewide aren’t charging Alabama’s 4-percent sales tax on clothing under $100, computers under $750 and other school supplies under $50 Friday through Sunday. News outlets report Alabama lawmakers voted to move this year’s tax-free weekend from the first weekend in August to the third weekend in July.

Melissa Warnke of the Alabama Retail Association said July is often a slow month for retail stores in Alabama. The Association’s 4,200 members hope to see a big boost out of the tax-free weekend.

Warnke says the sales tax holiday weekend in the past has been Alabama’s second-busiest shopping period of the year, with the busiest being the Christmas season.
