We had a new central heating boiler fitted a few weeks ago and having replaced a few bits fairly recently on the old one (bottom cover, thermostat knob and electronic control unit), I took them off and put them on eBay. They sold straight away (too cheap?) for £55 plus postage so, less PayPal and eBay selling fees, I’ll get about £45. Not bad for something that was going to be chucked away but........ when wrapping them up, I knocked our set of digital kitchen scales off the breakfast bar and broke them. Just ordered a new set. Same ones - luckily on sale now at half price so £25 instead of £50 otherwise I would have been out of pocket. Ballcocks!
