| Nine states and the District of
Columbia are doing away with the sales tax on items such as clothes, shoes and
even notebooks over the next few weeks, just in time for back-to- school
shopping. Most of the promotions last only a few days, so shoppers will have to act quickly to get a tax break. The tax holidays, which have already expired in two other states, apply to small and large items. For example, the tax break applies to any school supply that costs $15 or less in New Mexico. In Massachusetts, it covers most retail purchases of $2,500 or less. Stores may offer additional savings because these events "give retailers an opportunity to have a sale on top of what the state is doing," says Verenda Smith, government affairs associate at the Federation of Tax Administrators. No industry-wide figures are available about how much consume A. $10 million B. $47.4 million C. no statistics available D. nearly a 3 percent increase [单项选择]
