I think this promotion worked well for Subway, because of brand recognition, Americans can hardly walk down a street without seeing the bright yellow and green signage of Subway. Their promotions are nearly as famous as the name itself (example: $5 footlong) It seems only natural that when offering a buy one get one free deal with Subway that it would encounter success. While this promotion probably did not attract too many new customers, their image will continue to shine in the eyes of their customers, by offering free subs, with the purchase of one and a soda.
