This /. story, "The End of the Light Bulb?" just reminded me about a program that Toronto Hydro is offering. For all you Toronto residents, head on over to Home Depot before October 30th and get your 2 free CFL bulbs! I think they've also reduced the price for CFL bulbs if you want to buy additional ones.
I picked up my two free bulbs a few weeks ago just to test them out. So far so good! My only gripe is that they're a bit bigger than the normal bulbs I had installed, so they tend to stick out of the top of the light fixture I put them in.
