Local News Station Advertising

Today a local news station has called multiple business like mine to promote their business on their news station. They will post your business information on their site for promo. They claim that they will get 50 or more clients every month to your business. The catch is that the business will have to pay 160 dollars monthly for 12 months which is expensive at the moment. I think this is a well opportunity to gain more customer and to pretty much gain the money back and more due to the clients that they said will be new every month. I just need help just in case things get really out of hand. What steps I should take when it comes to something like this versus regular advertising/marketing. Thanks
