Why would the MBG not be a consideration?
It's relevant as people would buy from QVC as they can phone p and see on the TV. If they don't have online then they would not know about the other place to get it.
Too be honest I don't think it really makes any difference to a product like this. Of it was a high end, expensive item then it might do. Otherwise what shop sells it does not really matter for most people.
It could be a mix of ways of being paid as some people work for Ideal World and some work on a freelance basis like Andy Love.
How much they get paid I have no idea but I know many of them work elsewhere as well - Dave Bradford has a local radio show for instance and Debbie Shore writes sewing...
You would trust them as you usually still want what you ordered. I can't think of anytime when I have ordered something and it failed to turn up where I haven't asked them to send it again.
I don't think it will affect Create & Craft in the UK - it's no different from a manufacturer selling in some shops in one country and in others elsewhere. And some brands like TomTom sell on both channels in the UK.
