It is. They are probably urged at QVC to keep numbers of products they have to trash down to a minimum - that and the fact that the staff are probably low paid agency workers SOME ans I do say SOME of which could not give a fig.
If I have to return beauty items I always make sure that a good bit of the product is removed, items are opened etc as I think it woud be awful if they tried to sell on.
I think this is at its worst when it's earrings - I no longer buy from QVC - and cosmetics.
