For those who didn't see the item, he showcased a few people who got ridiculously cheap car insurance (some as low as a tenner!).
He advised viewers to get quotes using Confused.com, CompareTheMarket, MoneySupermarket and GoCompare.
The next step was to go to some "money back" company sites to (effectively) get paid to take the insurances out. The companies to which he referred were not simply the likes of Swintons, who offer "cash back" deals.
I've got as far as getting the quotes from the 4 x sites that he suggested (none of which are better than my current premium), but I've rather "stalled" on the "money back company" bit.
I haven't done it for the car insurance but I have bought other goods and services via the cashback sites and made a profit. I got my house insurance with Halifax via Quidco.
I like Quidco the best as they seem to give the most cashback... it takes a few weeks to get your money but they have been pretty reliable with paying out.
Yes, through Quidco i usually get �75 cashback on my car insurance. But it's a slow process. I got a �75 cashback last year from an esure policy and had to wait 10 months for the money. http://www.quidco.com/
Some insurers offer up to �125 cashback through Quidco.
To get the cashback you must make the purchase wholly through Quidco.
