I try and stick to the rule of not really flipping for profit, I wanted the wheelset off a bike I recently won on eBay, so I sold the remaining parts. I think I made a £15 loss when all postage was complete Etc. so in reality apart from my time & some gt85 the wheels cost me £15. Not bad seeing as they had a suprise m900 cassette lurking on there. It's when you get a total bargain off the bay then try and make mega bucks on here you start to look a bit of a tw@ IMHO
