Morrisons brand of energy saving bulbs are 2 for 29p. The deal is that you buy one pack and get two packs for free!!! so effectively 6 bulbs for 29p!! bargin. They are morrisons branded and are 11w equivalent.
Not a bad price.
I saw these in morrisons leicester, they may be nationwide, but im not sure. (there are at least 100 packs still there)
