Who could resist the offer of a free grand piano? Or a remarkably cheap campervan? Just as long as you pay for delivery - but that's a small price to pay, right?

This episode of Scam Secrets is about those times when you're offered something - perhaps something you've always fancied - on amazingly good terms. It's a scam - otherwise Shari Vahl, Dr Lis Carter and Alex Wood wouldn't be talking about it. Luckily they've got their red flags ready to tell you what to watch out for.

In this episode, Lis delves into the language used by the criminals - explaining how they trigger our desire for a musical instrument we didn't know we wanted - and former scammer Alex shares his insight into how people are manipulated by delivery scams like these.

The Scam Secrets guest expert is Dr Jack Whittaker - an academic who wrote his PHD on precisely this kind of fraud. He tells the team where these scams come from and how to see them coming.
