Preparing for Mothers day

Help me out here people! Mother's day will be a day after i return for semester break and I'll stop by the capital mall to get something for my mom. BUT here's an issue, what do you get someone who:
-doesn't appreciate fashion and wear anything comfy
-don't wear make up, perfume, jewelry
-don't have time to read but rather watch TV anytime
-doesn't cook
-sweet food is bad for her health
-don't appreciate flowers, aroma therapeutic candles
-has more body/face care products than i can ever imagine
-home deco, paintings, crafts? Meh~ forget about it. She doesn't know what are those.
well, i'm in a dilemma here. Almost everything i can think of is not good for her. I'm gonna give a card with one gift but I can't think of any!!
Can you give me some suggestions? Would appreciate it very very much!!
