Family Dollar complaint: Do not honor sale prices

I went in their multiple times where signs on soft drinks said they were on sale including today and had to fight to receive the sale price and there is a black cashier that was in their today as well that always fights me. Today she was the cashier last time she was just in the background talking. The cokes were advertised by stickers on the shelf for 2 for $4. The cashier said that was not their sticker. It does not matter whose sticker this is. It is a price advertised. She called the district manager and they agreed finally after telling them the law required them to honor the price to sell me two at that price. I will go to the attorney general about this store if this is not resolved. If they advertise a price in the store or in the circular they have to honor it. I have let them know this both times and they always give me excuses like the coke man put that sign there or they haven’t had time to take the sale price down or they have not had time to raise the prices or their machine is broke to change the price.
