The N.C. Attorney General's Office says, small business owners across the state are getting calls from companies, asking them to pay for advertising on public school athletic calendars and other booster items. Business owners are told that buying an ad will benefit the schools. Some of these companies, which are for-profit, take money for the ads but never produce the items and aren't endorsed by the school system. Officials say, before you purchase advertising or school-associated products from a salesperson you don't know, check with the school to make sure the fundraiser is legitimate. It's also a good idea to check with the local Better Business Bureau and the Consumer Protection Division of the Attorney General's office to see if the company has any complaints on file.
