Stack coupons to grab Garnier Nutrisse hair color for half the regular cost in stores at Dollar General. Download the DG app and clip two digital coupons: a $3/1 manufacturer coupon and a $1/1 store coupon. Redeem both of them at checkout and pay just $4 for a box of Nutrisse.
Since this deal involves coupons, it is not available for online shipping. However, you can place an order using free DG Pickup in the app. Not all Dollar General stores offer this service, so enter your zip code to find a participating location near you.
