Series one was first aired in June 2006 and a second series was later commissioned and began to air in June 2007. Series three began in June 2008.
This is achieved by Littlewood seeing hidden camera footage of a first attempt, and giving them pointers. After this they try another shop but this time Littlewood can communicate to the member of the public by means of a hidden earpiece.
The show also helps out people in need, who have been treated unfairly, to get deals or refunds on products or services. Examples from the series are people who have had their wedding holiday spoilt by the company they booked with and someone who was being "ripped-off" by their mobile phone provider.
There is also a section where Littlewood attempts to save a shopper he meets in the street money by haggling the deal himself.
