Northam, I think that's the publicity brochure rather than a sample. I got one of those brochures through a while back when I ordered some blades from the Shaving Shack. It's a fold out A3 job.
You give them your email address in exchange for a free sample of the product. They then send you "selected offers", so unless you have a "junk" email address (I use an old defunct hotmail email address) then I would not bother and if they ask for home address or phone numbers just leave it.
But its your decision..........
James, have you thought of PMing Dan from the Shaving Shack. He's a member here and might send you a sample. Worth a try!
For what it's worth it is supposed to be pretty good. I assume you have tried the cream. Well if you like the scent why not just go for it and give it a shot?
If it asks for things like phone numbers I would always make one up, I keep a different email address for companies I don't want to be bothered by too. SOMETIMES, just sometimes though some of these companies offer something worth while.
