Secret Dealers is a factual game show that aired on ITV from 27 September 2010 to 2 January 2015.
The bids are left in sealed envelopes next to the desired items and the offers are kept secret from fellow dealers until the homeowners opens them.
If they think it is worth more it will often end in a bidding war to see what dealer will pay the best price and take the item.
The show was revamped for series 3 with dramatic music and new titles with the presenter role dropped and a change in the format.
Another notable difference from 3 included several dealers dropped; leaving the eight most popular as chosen by members of the public.
