Dove Intense Therapy Shampoo BOGO free

I stopped by Dollar General, in Kenova, today and they had Dove Intense Moisture and Intense Therapy shampoos BOGO free for $3.50. I bought 2 and used 2 $1.50 off coupons. Got 4 bottles for $1 each. Not bad. I am sure others have the same deal but watch as they ring up. She rang mine up and they rang up $3.75. I pointed out to her the sign (which thankfully was in front of her) and she adjusted the price.
