In reply to Heike:
A bit off topic from your OP but to "save money" you need to spend less or earn more. Either or both!
There are loads of resources online for doing one or the other, both specific consumer advice like moneysavingexpert.com for things you have to buy, but other places for the psychology/philosophy angle of things you want to buy.
Some great blogs are thesimpledollar.com and getrichslowly.org. They're American personal finance blogs that have been running for years and have gone a bit downhill in terms of new content but have massive archives of great articles about getting more from your money. Sometimes you take your attitude to money for granted and don't realise what you've inherited from your family, or friends or culture around you, so it can be useful to see different perspectives.
In terms of actually saving though the simplist hack is "paying yourself first" which is setting up an automatic transfer to leave your account the day you get paid and go into savings, instead of relying on having something left at the end of the month. Then you live on the rest. Try it with even a small amount and increase it bit by bit.
Another method is that when you save some money or reduce your outlay some way (like switching a utility provider, or bulk buying something) put the difference you saved straight into your savings account. You won't miss it because you were managing to pay it before but if it's left hanging in your current account you'll just spend it on something else so it's not really saving. Lots of little trickles can add up.
It's a massive topic but have a rummage aroudn the net and see what you can find about things like the envelope budget method or balanced money formula. Sounds dry but getting control of your money really feels awesome and means you can feel less guilty about spending money on shiny things like cams
Interesting thread though - I'd never be able to put numbers on a public thread but enjoy reading about others - thanks for sharing
