My parent is a 96 year old low sighted senior who lives on her own. She is quite sharp on day to day activities but gets confused on things she doesn't understand. She evidentally received the letter with the coupon and placed it in a receptacle on her kitchen table. It is not where her usual mail goes. We asked her every couple of days the last months if she had gotten it as I had ordered it in late July or August. But she didn't know anything about it. My sister found it accidentally after it had expired. There should be some consideration for these special cases.
