This coupon was available a few months ago and it was "rumored" that using it would get you FREE Robitussin To Go Single Packs at WALMART. I personally NEVER found those "single pack" Robitussins in ANY Walmart within a 30 mile radius of my home. The coupon is available once again. If you find this FREEBIE please let me know. :o)
