I bought some Gillette Contour Plus blades from Sainsbury the other week - 10 blades at a sensible £8.00. Then discovered that the Contour plus razor I THOUGHT I owned had been disposed of. Fear not! I spotted that Boots sell a "Twin Blade System Swivel Head Razor" and 3 blades for only £2.45 and the Gillette blades fi on it. One razoer, 13 twin swivel blades with lubricating strip, £10.45.
