I went to use the free item for one of the 12 days and it said that I already had used it. I had not used it but the cashier made it worse by saying that computers don't lie. I was really offended by this and the other worker could see that he offfndedd me as I stood there with my mouth speechless. He jumped in and told me if I even opened the redeemed part after a amount of time it expires. I don't understand if everyone has a special code why would you need to do this and now the other worker thinks I'm trying to pull a fast one on them and get a 2.00 item for free. FYI I still paid for mine. He had no understanding and immediately ignored me and went on with his day.
