CINCINNATI — Shell Oil Co. has begun offering gas discounts to regular Kroger Co. shoppers in four Michigan markets, the first expansion of the companies' team-up.
Kroger loyalty card holders now can get 10 cents off a gallon at Shell stations in Detroit, Flint, Lansing and Saginaw for every $100 spent in Kroger stores.
Kroger spokeswoman Meghan Glynn said Wednesday that the companies are evaluating the next step in the program that began in February in Cincinnati; Dayton; Ohio; San Diego; Nashville; and Knoxville, Tenn.
Gas discounts are popular incentives for shopper loyalty amid tough grocery competition. Midwest superstore chain Meijer Inc., based in Grand Rapids, Mich., is among competitors that offer fuel breaks.
