I found a stack of these in my local ASDA all priced at 50p. A really good price considering the pack which contains one more blade was £3.98.
I find I do have to modify my shaving style, due to the blade size, compared to using a Fusion. But considering the blade lasts longer, and costs 1/3 the price of the Fusion blades, it's a compromise I'm happy to make.
Obviously I cleared the shelf in my local store, Kings Hill, but there's bound to be plenty more around the country for everybody else.
