Staying warm w/o power

If I were rich, I would donate a bunch of space blankets to organizations helping the people who are w/o power due to the storms in NE. They do not use electricity. They reflect your body heat. I have two on my bed, one I sleep on top of, one over my blankets. I wouldn't deliver the blankets myself, I would let the agencies get them an distribute them. Buying a bunch should enable a discount. I would also like to donate them to poor and homeless people.

I get mine at REI. I get the sturdy ones, which cost more, but last for years. I also use them on my windows. In the summer I use them during the day to out the warmth from the sun. In the winter I use them at night to keep the warmth from escaping.
