From The Belgrade Chamber of Commerce: Advertising Scam

It has come to the attention of the Belgrade Chamber of Commerce that someone is attempting to sell ads to Belgrade businesses for Customer Appreciation.  Customer Appreciation is on May 17th, not May 10th.  The only ads that are authorized to be sold for Customer Appreciation are Belgrade Chamber members.  There are nine authorized media outlets to do, with TownSquare Media being one.
If you have any questions about someone selling you ads, please contact the Belgrade Chamber at 406.388.1616.
