Does she have Netflix? This may sound crazy, but what about a Roku box? If money is tight for her, she may not want/can't afford to pay for cable tv. With this box, she could just use Netflix for $8.99 a month and they can all watch thousands of shows, movies, lectures, documentaries via instant streaming. If she already has Netflix, I think it is a great gift for a family. They are about $60.
I am thinking of doing this for a friend who is a single mom and who already has Netflix. She wants to cancel her cable because it is so expensive. Around here basic cable is $13 a month as opposed to $65 for just expanded basic. This alone would save her over $50 a month and the selections are huge.
May be a little unusual, but sometimes it is fun getting something totally unexpected and out of he ordinary.
