Here is a great deal to go with that $1.00 off THREE KRAFT Macaroni & Cheese Blue Boxes coupon available right now. This one is good at Walgreens through the end f today 2/2:
Kraft Macaroni and Cheese $0.89 per box
Use $1.00 off THREE KRAFT Macaroni & Cheese Blue Boxes
Pay 56 cents per box when you buy three boxes
This is the cheapest I see for this at the moment. I saw the boxes of Mac and Cheeese for $1 at Target too.
