We at Reduce Your CO2.com are always on the lookout for green bargains, and one of our favourites is the energy saving light bulb. It also seems to be a favourite with the big stores, as Tesco is now following in the footsteps of B&Q and The Sun (plus various supermarkets) with an offer of up to 4 low energy bulbs at 1p a piece.
I’m off there asap, and if your house isn’t yet fully equipped, I suggest you do the same! I would have hoped to see more details about this on their ‘Greener living’ web site, but no, so you’ll just have to pop along to your local store to see if it’s taking part and if there are any left. Good luck!
