I know this was about £3.50 a month ir two ago but this is still a good offer in my opinion.
A Wilkinson Sword Hydro 5 which comes with 2 blades and you also get a pack of 4 extra blades for the resonable price of £7.90
When you think about it the razor itself is £8.16 and the refill pack is £7.65, so you are saving about £7.91
I bought mine instore (there was other Wilkinson Sword on offer but can't remember them)
Just a good deal still in my opinion
