Difficult to return items. I ordered heat tech tights online and the size was too big for me. Tried to exchange in store but wouldn’t accept because I have opened the packaging (explained that I had to open to try it on, obviously). They didn’t allow me to return it at all. Advised to return it online - in which I have to pay the return postal. I am not even sure if I will have the refund due to the open packaging?! How would I know if it fits?
