Glucerna Back Again! 03/21/2009 By Charlene Leave a Comment This post may contain affiliate links, please see my disclosure policy. Thanks to Money Saving Mom on this great tip to get even more Glucerna cereal for free. This is a great item for your dination box if you don’t know someone that is diabetic. Looks like Walgreens is offering a $2.50 catalina on 2 boxes. Don’t forget to submit your receipts to Caregiver’s for another $1 per box rebate.
