Britain's biggest supermarket chain is cutting the cost of its female razors to match the same product sold to men. Tesco said it had come under pressure from British lawmaker Paula Sherriff after it was found to charge twice as much for pink disposable twin-blade razors as blue ones. The products are identical excepts for color and price. Tesco had defended the pricing by arguing that it sells many more men's razors, making it easier to keep prices low.
