When I learned of the planned government mandated phaseout of 60 w incandescent bulbs it was a year or two out so prices had not gone up in the stores. I bought a lifetime supply of them for chump change. Got a lot of 4 in a pack for $1, most all of them little more than that. Basically, for about $20 I have more than I will ever need. Especially since now the LEDs have come down so much that I have put those in the hard to reach fixtures & I only use the incandescent bulbs in the rest.
Incandescent uses more power ( money) than LED.
