New $3/2 Robitussin Coupon = Better Than FREE Robitussin to Go at Walmart!

I just spotted a new coupon on Coupons.com for $3 off 2 Robitussin products.

Walmart sells the Robitussin To Go for around $1 each. I have seen these at the Register before, but you may find them in the medicine section as well.
