Actually, I changed jobs lately and am now working 4 miles from home instead of 25. That means my petrol bill has been reduced from £180 a month to less than £60.
Further, because I'm only working 4 miles away, I've started cycling to and from work, which means we've become, once again, a one car family...being able to shed a car and all the bills that go with it has meant the savings have been going up.
In the first 5 months of this year, when I worked 25 miles away, my wife and I pumped £1300 into both cars just in petrol. In the latter 5, whilst working closer to home, we've spent less than £500. So I decided to use some of that money on a new computer
Still cycling. Great fun AND quick AND cheap AND great for your health.
