To get this do the following.
add No option (Free Pace 6 plus handle + 1 blades + £1.95 delivery) then continue shopping and then
add (Free Delivery) Pace 6 Plus Replacement Blades x 8 +£13.59
as you get free delivery that makes the top blade free then go to checkout and add code welcome5 this make the whole package £8.95 delivered.
I have done this and started using the blades and they are very good better than cornerstone and probably as good as Gillette (time will tell on that though)
