TULSA, Okla. (AP) - For the second consecutive year, back-to-school shoppers in Oklahoma will be able to stock up on school clothing without paying sales taxes.

City, county and state sales taxes will be suspended next weekend during the state's annual sales tax holiday. It will run from 12:01 a.m. on Aug. 1 through midnight Aug. 3.

The Oklahoma Tax Commission says shoppers saved $6.4 million during last year's sales tax holiday. Shoppers are expected to save up to $6.6 million this year.

But the tax commission says it's hard to predict how many people will take advantage of the three-day event.

In Oklahoma the tax exemption applies to any article of clothing that costs less than $100. Accessories and special clothing or shoes designed specifically for athletics will be taxed.
