There's a new 50c IP for Wacky Mac here
Shoprite has the Wacky Mac & Cheese on sale 3/$2 Must buy 3.
This coupon is a DND 5, but the DND is in fine print so this will definitely be a YMMV type thing.
Buy 3 use 2 50c/1 IPs fully doubling and get these free.
Buy 3 use 3 50c/1 IPs no doubling and pay 50c/3
If you try this out please let us know how the coupons were handled!
