I'm new to this site, so please go easy!
I have just bought King of Shaves shaving oil for I think around £2.95. BUT inside is a money off voucher which gives you £1.00 off the Azor razor.
I then went to superdrug, who have the Azor with 3 refills on sale for £3.66. I used my £1 voucher and got it for £2.66!
It gets better - inside my Azor pack is anoth £1 off voucher for any pack of refills!
Oh and it's a great razor - I was using the gillette fusion and wilkinson quattro before, but this razor is great, esp if you have designer stubble like me lol
