Roy - it might be saving because of the 15% VAT rate.
I have just bought two more today - an AA and a C, and I have two C ones already (minus front lens caps, that I've lost).
Excellent torches, and good for lighting photos (which is why I have so many). I have submerged mine with the front caps off and the bulb exposed, caked them in sewage, orange gunge and snow but they still work!!
