Bic are currently offering a metal version of their Flex Hybrid 5 for £2.00. It requires a subscription which can be cancelled immediately.You get one razor and one cart. I haven't used mine yet, but I wasn't impressed by the Flex 4 disposable. Gillette are also offering a Fusion FlexBall manual for £1.99. This includes a £4.00 off voucher for Fusion blades. Wow, these are now expensive.
