Any recommendations for good sites to buy safety items to keep in your car during the winter? There seem to be a lot of expensive options out there. I tend to keep some supplies in my car and would buy some stuff like emergency "space" blankets (which are affordable). There are a lot of other items suggested on some lists of what you should have, but they seem to link the most pricey stuff available. So, where are the good deals on winter safety supplies? Any ideas?
