As the text indicates, “CouponFactory is about keeping things easy -- for marketers and for consumers. The turn-key system, which Rockfish Interactive launched in April, allows marketers to create and distribute digital coupons using simple templates, and then embed them anywhere (including Facebook); consumers can print them out without special software -- and whenever the coupons are redeemed, CouponFactory serves up rich analytics that can be used to tweak future campaigns. National brands using CouponFactory so far include Schick, Mentos, Mott's, Glade, Boston Market and Tyson.”
