New Theraflu Coupon=Moneymaker at Walgreens

There is a new $2/1 Theraflu coupon available here. Using this coupon, stacked with a Walgreens coupon, and getting back register rewards making this deal a moneymaker. Here's the details:

Buy (2) Theraflu Cold Relief 2/$10
Get back $3 in Register Rewards
Use (2) of this $2/1 coupon here
Use the $2/1 Walgreens coupon from the Health Savings Book (will deduct $4 at the register)
$1 profit after coupons and Register Rewards

When I bought mine, in order to use the Walgreens coupon, I had to purchase the Theraflu 6 pack drinkable medicine. (since that was the picture on the coupon?) I'm not sure that will be the case at all locations.
