My Vons store has a special price on a four pack of compact florescent bulbs for 99 cents- no club card needed. One bulb is normally around $5 each. There is a logo on the front that says they are being subsidised by SDGE. Four 100 watt equivellent bulbs that use 23 watts of energy. Save on your utility bill and they last longer than the older type of bulbs too- "Lasts 10 times longer" according to the box. Says guaranteed to last up to 7 years.
