OTTAWA, Ill. – Two Supervalu-supplied independent grocers, Handy Foods here and Newton IGA, Newton, Ill., have partnered with Excentus Corp., a fuel site marketing programs provider, as well as with local Marathon Oil to introduce a cross-marketing program that gives consumers discounts on gasoline at Marathon Oil for purchasing certain products at the grocery stores. The program, branded as “Pump Perks” in both locations, is managed by Supervalu’s regional office in Kenosha, Wis., and began yesterday. The retailers use the Excentus reward-marketing engine to track purchases of promoted items and the subsequent fuel discounts. This technology connects the grocery store with the partnering Marathon gas station nearby.
