Found 2nd Jan 2017
Went to John Lewis today to buy my first Hue colour bulb to go with my white ones I already have. Price scanned at £24.98 instead of £49.95 which the shelf edge label shows. Checked both screw and bayonet fittings and they are both scanning at £24.98. This was at the Bristol Cribbs Causeway store. Maybe just this store or could be a national thing. There were 5 bayonet bulbs left there this evening.
