If the link says "£10 off" - and nothing else - and doesn't make it clear that you're actually signing up to something, and your credit card details are being passed to a third party, then it seems pretty deceptive to me.
That's why so many people have unwittingly signed up to schemes which they only found out about some time later.
If you hit the "reply" button to this post and the same thing happened to you, would you be happy about it?
