I agree with Matt that self-stick foam is a really great option. Definitely get an option that is most weather proof. Frost King is pretty good. Stay warm this winter!

You could try something very simple like this. It will at least help the draft at the bottom!

I put this stuff around my door and it worked to some success. The main problem is that it doesn't stick very well. Within about half an hour of putting it up it started falling down! So with some small picture hanging nails I banged it back on there and it has stayed ever since.
It noticeably reduces the draft of cold air. If I put my hand over the one spot I wasn't able to cover I can feel the cold air coming in...the rest is sealed pretty well.

Using a self stick foam is a great option and inexpensive for insulating doors. It's a pretty simple process. Just measure your door frame, cut, and tape the foam to the inside face of the door jamb. All done.

These work ok, and I think they are worth the price for the insulation they provide.
The only annoying thing is if the fit isn't just right it will keep getting snagged. Like it works on my front door just fine but on my back one the frame is a bit funky and so it get caught on it. Besides that it's a pretty good little device.
