The Martin Lewis Podcast is here – founder of Money Saving Expert, Martin Lewis answers your financial questions.

What is Grey Friday? When is Cyber Monday? Martin reveals whether Black Friday is any good. He shares the best and the worst type of deals – plus his take on pre-Xmas, Boxing Day and January sales. But before you get pulled into an impulse buy, Martin coaches us in his ‘Money Mantras’ and ‘Black Friday shopping memo’.

This week, listeners Sheena and Aimee got in touch to ask about interest on Help-to-Save and energy bills. Elsewhere in the podcast, ‘Tell Us’ the most expensive thing you’ve bought but never used.
