This requires you to set up a subscription but that can be cancelled if you want (might be worth waiting until you've received them as the first order is part of the subscription. Mine only took 2 days to arrive). However, these blades are great - just as good as the Gillette proglides but a lot cheaper. So you may just want to subscribe. You can change the delivery frequency up to four months. Even the £5.95 every 4 months is a great deal for decent razor blades in itself.
