Was in B&Q tonight and they were marking loads of lighting down to between £1.00 to £3.00 each.
some of the lights were £60 down to £3
various colours from white , brass and chrome
i brought the cirrus dimmable halogen spotlight 4 light plate down to £3 from £30
think it is just instore and i think it is nationwide as i over heard another customer say they picked up some yesterday at another store.
hope this helps someone out.
