Better hurry. I'm hoarding them and have been for a couple of years now. I've got a couple of cases on the shelf now. There are some uses, like providing heat in my well house during winter, or spot heat when I'm doing a composite repair, that I cannot get from a florescent. I buy three or four packs of 100w bulbs every time I go to Lowe's or Home Depot. I've noticed that the amount of incandescent bulbs on the shelf in the stores has diminished considerably over the past few months.
Stocking...I have been getting bulbs every time I shop for the last year.
You can get incandescent light bulbs rated for 25,000 hours that are used by the hospitality industry. If you use them for an average of 7 hours a day they’ll burn out in just a little under 10 years and cost about a buck or less per bulb depending on how many you buy.

Once you stock up all you’ll have to do is watch out for the light bulb police who’ll be monitoring everyone who might be using those unauthorized, evil incandescents!
