When I was growing up, a man's word was his bond. Supercuts would not honor a current, valid coupon I had received just two days before. I later asked for a refund of the amount of the coupon ($7 off) presented prior to payment and am still waiting.
This is now an update. Supercuts said they are mailing me a check today for $7 so I am now satisfied with their response. The franchisee was very responsive. I will be returning there to get my haircut in the future.
