Saw allenhori's deal for the OneBlade Pro shaver. As I already have a shaver, I was looking for the replacement blades. Noticed these are now on sale and slightly cheaper with S&S option.
Update: Price increased from $35.61 and S&S $32.05
Update 2: Price back down to $35.65 and S&S $32.09
the 3 pack is 42.03 from amazon UK if you find something to get you over $49 for free shipping
