False Advertising / Rude Service

Today my mother and I spent over 2 hours trying on clothes. I had over $300 picked out and my mother had about the same. We saw a rack of sweaters and jackets. There was a sign on the rack thats stated "All sweaters buy 1 get the secon 50% off" All of the jackets and sweaters were tagged with a red tag that stated the same thing.We each picked out 2 jackets. When we approached the cashier we were told that the sale did not include the jackets even though they had the same sale tags on them. The store supervisor walked up and told me that I needed to learn to read and rudely turned and walked away. My mother and I each laid down our purchases and informed the cashier who WAS trying to help us we would rather give our business who valued their customers.We did not buy anything nor will we ever buy anything at this store again.
