Many beverage manufacturers promote their new lines and line-extensions heavily with their new distribution channels. And Spring and Summer are prime seasons.
Team up with a beverage manufacturer to host a vendor-funded campaign. Partner with a local retail location such as a supermarket or convenience store that has just begun stocking the product. (Your beverage company rep can tell you who their new partners are.) Create sampling, BOGO, couponing, and loyalty options to keep the consumers who listen to your station(s) coming back for more!
