what I'm not good at

I'm not good at houses, but this weekend I have tried to move a stage more ecofriendly by changing the rest of the light bulbs to low energy ones, and sticking heat reflectors down behind the radiators. Changing bulbs is so simple, it's the centrepiece of jokes, and the radiator panels' only technology is the double sided tape, but you wouldn't believe the mess I made. One disappointing thing is that I ended up sending away for the bulbs and the radiator panels. Does anybody know where to buy them within walking distance? i ordered them all through the Shimna website and Natural Collection, which gives a good percentage to our fundraising.
