Walgreen's

Children's Advil buy one get one 50% off 
4oz liquid $6.99
- $2/1 Walgreen's coupon found in the Infant Care coupon booklet will deduct $2.00 for each bottle
-$2/1 coupons found here
-$5.00/3 8/14 RP

I did this today on it only took off $2.50 for the 1/2 price bottle. The only thing I can figure out is that when you use the Walgreen's coupon it adjusts the price down then it will take off 1/2 which would be $2.50. I still think that $10.19 for 4 bottles of Advil is a great price. The tax was $2.23.
