This is something I've always wondered. That qvc is known nationwide, and anyone must have lived on Mars if they've never heard of it, even if they've never watched it.
So, given that the presenters are all mostly 'long stayers' and are 'fairly' well known, then why haven't some of them appeared on various mainstream shows ? whether its quiz programmes (celebrity pointless?) or even interviewed on a morning magazine programme ? I mean, Julia R would have relished the opportunity to plug her books on Loose Women or This Morning, and Flinty would have a field day self publicising, therefore, like you say DF unless there is a clause in their QVC contract that forbids them from doing it, I cant understand why it hasn't happened.
