Iowa’s Attorney General says a new multistate agreement should help cut the sale of cigarettes and tobacco to minors. Attorney General Tom Miller says Wal-Mart — the nation’s largest retailer — has agreed to institute several practices in its stores aimed at preventing the sale of tobacco to minors. Some of the things the retailer has agreed to include: checking the I.D. of any person trying to buy tobacco that looks under 27 years of age, hiring an independent entity to conduct random compliance checks at 10 percent of the stores every six months, and prohibiting the use in stores of self-serve displays and cigarette vending machines. Wal-Mart has over 34-hundred stores nationwide, including 60 in Iowa.
