Should you rediscover thrift?

The PM - while guzzling eight-course meals in Tokyo - wants us to waste less. And he's right. Take credit cards: they're very expensive.  So how can you make sure you pay as little interest as possible?

It is getting harder and harder to dig up any sympathy for Gordon Brown. Here we all are at the beginning of what looks like it will be one of the most unpleasant economic periods for decades and he suggests we ease the pain by eating more left overs.

"If we are to get food prices down," he said as he left for the $280m G8 meeting of global leaders on Sunday, "we must also do more to deal with unnecessary demand such as all of us doing more to cut food waste which is costing the average British household about £8 a week." It is of course absolutely idiotic to think that UK consumers can move the price of wheat by eating mouldy bread any more than to think we can affect the temperature of the earth by taking our TVs off standby. But on the plus side, at least Gordon seems to be getting the hang of the prudence thing at last, and I suppose saving the £8 a week - £416 a year might go some way to help with our rising fuel and supermarket bills.
