It's got easier to win big on the Premium Bonds but should you invest?

Premium Bonds are a national institution and their prize-giving place in British savers' hearts was only cemented further through the low interest rate years.

But now interest rates are on the rise and Premium Bonds offer not only the chance to win £1million but also a much better rate of return.

The average prize fund rate on Premium Bonds has reached the heady heights of 3.3 per cent - going head-to-head with top easy access savings deals.

But what many savers may not realise is that their chance of winning a big prize of £100,000 or £50,000 has got much better too.

So, is it time to back Premium Bonds even further, or would you be better off with a standard savings account? On this week's podcast, Georgie Frost, Sam Barker and Simon Lambert look at the numbers and the pros and cons.

Plus, an even better return of up to 4.6 per cent is offered now by five year fixed rate savings accounts, but are they worth going for and choosing over stocks and shares?

This week brought yet more news of annoyingly high inflation, as CPI stubbornly stuck above 10 per cent, but why are food prices still rising so rapidly, are supermarkets or producers cashing in, and what can you do about it?

And finally, supermarkets have a new loyalty card wheeze - lower prices for those with them and more expensive groceries for those without. Sainsbury's Nectar Prices has followed Tesco's Clubcard Prices and now the Co-op has member prices too. 

Is this enough to change Simon's mind on loyalty cards?
