I was in a Ganahl lumber earlier. They have compact flourscent light bulbs for $0.20 (yes - twenty cents!!!) with a limit of five per person. I got my five!!
It appears that this is sponsored by So Cal Edison. I don't know if anybody else (like Home Depot) is participating in this.
There are eight Southern California Ganahl locations: Anaheim, Buena Park, Capistrano Beach, Corona, Costa Mesa, Laguna Beach, Lake Forest, and Los Alamitos. Find the one closest to you
