WWD:Wal-Mart is the latest retailer to cover Cosmopolitan, according to the National Center on Sexual Exploitation, the organization in charge of a campaign to conceal the covers of the women’s magazine. A Wal-Mart spokesman confirmed the news adding: “Wal-Mart has provided these blockers to our stores so this isn’t anything new, but we are sending out a refresher communication on their use.” Wal-Mart follows retailers Rite Aid and Delhaize America, owner of Hannaford stores and Food Lion, in putting the magazine “behind blinders” in their stores “due to the magazine’s inappropriate content and covers.”
