This week HEB has Hamburger Helper, Tuna and Chicken Helper on sale $5/5. You can also print out an IP from the Betty Crocker website for $1 off 3. This makes it .66 a box.
I also noticed Aleve pain reliever for $3.97 that is the Christmas package...buy one, give one. You can use your $1 coupon, making this a nicer deal.
