Martin Lewis is urging people to spend £1 which could then see them save hundreds of pounds this year.
The Money Saving Expert founder told viewers of his ITV programme Money Show Live on Tuesday that the "trick" is all to do with Compare the Market. People, he said, can make huge savings via the price comparison site.
After spending £1, you can get buy-one-get-one free cinema tickets for a whole year.

Mr Lewis said: "Five Vue cinema tickets, £20 via Groupon, or 2 for £9, 10 for £38. Check your local cinema prices to see if it would be a saving, some only cost a fiver, some cost £12.
"By the way, the easiest way to get that is to get £1 daily UK travel insurance, and then you get the 2-for-1 cinema tickets for a year without having to get anything else with that. But if you get this, the five Vue cinema tickets is relatively cheap."
Birmingham Live reports Mr Lewis said all you need to do is go to the price comparison site and take out a single day's travel insurance. Prices start at £1, and the policy will then qualify you for two-for-one cinema tickets for an entire year.
There's no requirement to use the tickets all at once either, meaning they can be split over several trips.
