I agree with PP. If she doesn't have a membership, try ordering online from Walmart. It costs more upfront but I think they have a 6 pack that works out cheaper and has free shipping. Also, I use Target's and get 5% off with their redcard debit card (doesn't pull your credit). I've never seen a coupon for a store brand.
ETA: I haven't tried this but it might work. I don't know if it's for all store brands or not
