You've spotted a nice cardigan on social media - the website looks legit. So you buy one. It doesn't feel like a scam...

In this episode, Shari Vahl and the Scam Secrets regulars - Dr Lis Carter and Alex Wood - unravel a global scam that relies on people buying pieces of clothing they've seen advertised on social media. As the team find out, what arrives is very much not what they've been hoping for. Who is doing this, and why? And how do you spot the red flags that mean you'll be bitterly disappointed if you click 'purchase'? But this is a scam that goes way beyond a rubbish cardigan and the criminals aren't just after your money.
