Having read the article, I have several things to add here.
You are told quite clearly, in fact the viewers are told "you have half and hour" to get the goods, its no secret!
We were met early in the morning by Tim W, who was the nicest person ever. He arrived before anyone else on the team, bright and breazy. He introduced himself to me and my friend, we had a cup of tea, fantastic!!
Our oponents had a new girl and we had the chubby miserably one with the red cheaks, can't remember his name now but he was miserable and told us "if you think you're going to get a bargain, forget it" I did winge about him to the production crew and that was that but apart from that, we could say what we wanted, maybe because we were a bit more in touch than the old couple giving the interview. We could add lib, whatever!! I chose the best item, not the fat one, my pal chose the other one and he chose the one in the middle, nothing odd about that. Yes the production crew have to whip it all off afte the show, of course they do!! They film two shows in one day so there are two teams of four and it was brilliant, so its all lies!!! lies lies!
Best thing to do is go for it yourselves and see.
