Martin Lewis made his way back on our television screens on Tuesday night for his last hour long special of the year.
While answering questions live, he spoke to one consumer, Josh, who was approaching the end of his mobile phone contract.
"I'm paying £26 a month right now," he said.
"But my contract is about to expire - so where should I switch to next?"
In a bid to save money, the fan explained he's keen to take his custom elsewhere to save money on his next contract - to which Martin replied "now is the best time".
"This is a good time to ask Josh as Black Friday has seen lots of hot deals.," Martin explained.
"Off the top of my head, Three is offering 8GB of data for £8 with unlimited everything.
"Virgin Mobile is also offering 10GB data, 5,000 minutes and unlimited texts.
"There's also Smarty - a product of Three - which is offering 45GB data and unlimited everything else for £15."
Complete with all-you-can-eat minutes, his top Three deal is available on a 12 month contract for £8 a month, with no upfront cost, working out at just £96 for the entire year.
Martin Lewis originally revealed the news on Good Morning Britain earlier this week, alongside a slew of other Black Friday deals, including the Smarty SIM only deal that gets you 45GB data, unlimited minutes and texts for just £15 per month on a 30 day rolling contract - meaning you're only tied to the tariff for a month at a time.
If you're looking for an 8GB SIM only deal, we spotted an even cheaper one on Plusnet, although it's a tad more complex than Three's.
Working out at £7.92 per month, it's essentially 8GB of data for £10 a month - but with a £25 prepaid Mastercard that you can use in most places. So while it is 96p cheaper than Three's altogether, it's also slightly more faff.
