Participating products (screengrab from MCR site):
Shop at a Giant Eagle, Lowes Foods, Stater Bros., or Stop and Shop? Those are the four listed as linkable to your MCR account. Just make sure your card gets scanned at checkout. It can take up to 48 hours to have your points credited. Also, this is a BETA program, so there are just a few retailers. If the program goes well, who knows! It may roll out to a lot more stores in the future. If it makes you feel any better, I have none of those stores near me. I do have a Giant (in the family of a Stop & Shop), but I don't shop there very often. See more of their FAQ's on this offer.
