Businesses in the Alexandria area should be aware of a possible advertising scam.

The Alexandria Lakes Area Chamber of Commerce issued an alert on Tuesday afternoon, Feb. 18 about an individual who is calling area businesses from an unknown phone number requesting advertisements for sports posters for the local high school.

The individual does not provide sample pieces for businesses that have supposedly advertised previously and offers an invoice to make payments.

The chamber's advice: Know who you are doing business with and what you are buying. Know your sales rep, ask questions and be aware.
