When you join the Kroger Community Rewards program and designate MAUBC, Kroger will donate a percentage of your qualified purchase to MAUBC. Kroger Plus cards are available at the customer service desk. If you use your phone number at the register, call 877-576-7587 to get your Kroger Plus card number. REMEMBER, purchases will not count for MAUBC until you register your card at krogercommunityrewards.com (Have your Kroger Plus Card handy). THANK YOU!
