What do you use the promotional codes inside Butterfinger wrappers for?

Customers can use the promotional codes inside Butterfinger wrappers toward current Butterfinger or Nestle promotions. The company prints codes even when there are no live promotional activities, and customers can save them until a new campaign starts.

Details of new promotions are available on the social media pages of the products and company, so interested fans and consumers may wish to subscribe to these feeds for further information. As of April 2015, there are no live promotions, but previous promotions included prize giveaways that consumers could access by calling the hotline number provided on the candy bar's packaging and through social media.
