Crystal Light Pure boxes, $.75 each, combined with the $1/2 coupon from Walmart's website (or even better if you are lucky to have the $1/1 blinkie)
makes them either $.25 each or free (if you have the blinkie)

Near East boxes of flavored couscous $.25 each. (they had wild mushroom and basil flavors)

Clorox Washing Machine cleaner $.50 each (I remember seeing a coupon floating around for it but I can't find it in the database, probably make this free or less than $.25.
