On October 8, 2007, Ohio Attorney General Marc Dann filed a complaint against Citibank South Dakota, N.A., Potbelly's Sandwich Works, LLC, and Scott Simmons for alleged violations the Ohio Consumer Sales Practices Act ("CSPA"). The case involved a flyer that was allegedly circulated on the campus of the Ohio State University promising a free sandwich. The catch, however, was that customers needed to sign up for a credit card through Citibank to redeem their free gift.
