I'm watching this show with anticipation hoping that one day an LED collector will submit their watch or collection to the dealers offers. That would be fascinating.
Go on - I dare you
To any overseas readers the show has 4 Rooms each with a dealer inside that trades/collects objects that are a little different than the norm. The prospective customer visits each room in any sequence to see what offer each one makes. However, they can only visit each room once and if they leave it without taking the offer they cannot return to it because the other dealers offered them less. That is the gamble - sometimes they get greedy and turn down a good offer thinking they will recieve more only to find the other dealer(s) offer them less - a lot less in some cases. Very odd items go through i.e. A nose cone off a Concord aeroplane, autograph collections, a stuffed Polar Bear.
You can find clips on YouTube if you are curious under "Four Rooms"
Any volunteers? Not me I don't have enough of a Poker Face

Best thing since the Sun Dial.
