If i sign up for a Nectar car will i get any junk mail from it? Do they p on details to other companies?

umm i'm sure if you tell them you don't want any newsletters etc they'll not send you any unnecessary junk mail.. and yes they can p on your detail to other companies but you can request to tell them not to... Like sometimes at the bottom of a letter that they send you usually when you have to fill in your details you'll see tiny tiny writing and a box asking you if you wouldn't want the company to p on your details then you'll have to tick the box.. it's unfair that they make the text so small lol
