I'm in my 10th year of watching, and this has been a constant problem. The presenters prattle on and then its as though someone in the Gallery has woken up and yelled in their earpieces "SIZES !", because then suddenly its " Oh I'd better give the sizes that some of you are waiting for" - then, as someone has said, its on the verge of selling out.
If QVC do read these comments, then this PROBLEM should be at the top of the agenda.
