I have tried to buy 100w lightbulbs without any success a couple of times now in the supermarket. I presume they are trying to encourage people to buy greener lightbulbs, but does moving from 100w to 60w make that much difference?
And before you all flame me I need 100w bulbs when reading otherwise I get a sore head.
I am quite happy to buy energy saving bulbs, but they aren't that easy to find either without going to B&Q or the like.
