Family Dollar

I downloaded my digital coupons for the Febreze, Mr. Clean, Swiffer, 3.00 off of 10.00 purchase, when I checked out it would not take the 3.00 off. The store manager verified that I had the right products. She said she couldn't override the price that something must be wrong with the app. Also I purchased Sparkle paper towels 1.00 off, same thing. I bought the things anyway, but it's very disappointing to take the time to do the downloads and then they don't work. You owe me 4 bucks.. [protected]@gmail.com
