In Money Box this week:

Will the banks finally have to go to court to justify charging us £30 or more to bounce a payment or if we sneak over our overdraft limit? One barrister tells us how he hopes to make them – at the risk of his own career.

We go out with the shark busters in Birmingham as they help local people to avoid illegal loans.

Tesco, Britain's biggest retailer, says it is not reviewing its policy to exclude thousands of low income customers from using its online grocery service.

We hear the controversial views of a car financing expert on the best way to buy that new Spring car.

And there's new hope that investors will be protected if they buy riskier products from foreign firms after the Financial Services Authority heeds warnings of another financial scandal.

That's Money Box – live on Saturday at noon, repeated Sunday at 9pm and any time (after midday) on the web.

Best wishes,

Paul Lewis
