Woo Hooo! I win! I win! I started DE shaving to save money. I looked at the price of the WS Xtreme III disposables that I had been using, just about the cheapest triple blade I could get in Sainsbuy's. Approx £1 a go in 4 packs, and about 6 shaves per razor, less if Mrs Slowblade got at them. I bought my WS Classic DE with 5 blaes for about the same money. 5 blades and 25 shaves later and I think I'm at break even point. I can now carry on feeding the Classic at 18p a blade, a saving of 13p every day! At that rate I'll be able to afford that shiny Edwin Jagger razor I have my eye on by Febuary and a half decent brush by next summer. Woot!
