My first post, so apologies if I've made any mistakes.
I noticed in my local Asda this evening (Govan) that they are selling a pack of 10 energy saving lightbulbs - bayonet fitting, 11W - for £2. The brand is General Electric "Mini Eco". These normally sell for £1.99 per bulb, so it seems like an amazing deal!
The woman at the checkout said that it's a short-term special offer and that when they're gone, that's it.
Hope this helps someone. Sorry I've no picture, but the same bulbs are sold on the following website, here: http://www.energysaverlightbulbs.co.uk/
so maybe someone could insert a photo for me (I'm not sure how to do it!!).
