Shoppers have enjoyed cheap prices off the back of a supermarket price war, but alarm bells were sounded in Sainsbury’s results this week, showing how cost inflation is squeezing its profits.

How long is it before supermarkets give up trying to cushion the blow for households and price rises hit?

Simon Lambert, Lee Boyce and Georgie Frost look at what next for our shopping bills and how the big supermarkets are doing, in this week’s This is Money podcast.

But how much do we really care about those big chains? It’s independent shops that we say we love and the team also take a look at whether the High Street is changing for the better or worse.

Also on this week’s show, we reveal the tax breaks that you just lost as the Government quietly dropped plans to let you earn a bit tax-free on the side.

There’s also a look at why 4G mobile is so shonky, rip-off bank charges and whether the house of 0% credit cards will come crashing down.

And finally, if you’ve got a parking ticket recently we explain how to beat it… and also why you might be getting more of them.
