Family Dollar review: Coupons

I went to Family Dollar. Bigelow Tea bags were advertised two for six dollars. The one dollar did not come off the purchase. The Manager would not resolve the issue . I had to file a complaints. She did take the incorrect sale sign down but told me she could not honor the coupon deal ! It was my loss. I told her I would file a complaint. This store always put up misleading sales. I would like this matter resolved and that manager spoken to.
