Bubble wrap your windows
Build It Solar has an updated piece about putting bubble wrap on your windows to help improve their insulation. According to the article, bubble wrap is often used to insulate greenhouse windows in the winter and will increase your window's R value from a 1 to a 2, which is equivalent to changing a single-paned glass window to a double-paned.The installation is quite interesting. Cut the bubble wrap to size, spray a film of water on the window with a spray bottle and apply the bubble wrap. To get some bubble wrap for free, contact furniture stores who will often give it away. Be sure to read the article to find out the caveats about removal.
Sounds reasonable, but I think having bubble wrap on my windows would make me more cranky than being cold. The author notes that even if guests come over (and presumably are going to think you are weird for putting bubble wrap on your windows), it is easy to just take it down and pop it back up again when they leave.
