1. These emergency blankets costs less than 80 cents each in bulk. Great for winter travel (ie upcoming storm), backpacking/hiking, any disaster prep kit. There are lots of brands, but the cool thing about these is they are very affordable, and lightweight -- you can stick one or two in your car, throw one in the desk at work, put it at the bottom of your backpack or briefcase. These work great also as emergency signaling devices (they are big, and shiny!)
