Click on the "print coupons here" link above and choose the "healthcare" link on the left. Look for the $2/1 Theraflu coupon. Choose it (and any others you will use) and then click on the red "print coupons" button. Hit the back button & refresh to print them all again.
Buy 2 Theraflu
Use two $2/1 from above
Use the $2 coupon in the Healthy Savings Booklet (will deduct $4)
Pay $2 - get $3 RR ($1 moneymaker)
Once you've used up all your printables you can use two of the $1.50/1 coupons from the little coupon machine in Walgreens instead of the $2/1 to get the Theraflu free.
