Based on your ability to harm yourself with a bike you should probably pay people to take it away and take up tiddlywinks
After months of arguing with the missus about buying a boat, snapping my arm riding a bike seems to have convinced her very quickly that a boat might be a safer hobby!
Lots here too, but not got a scooby how to price things
ebay-20% (as its fees are 10% and postage on top of that), I'm going with £1/£5/£10/£20 boxes and rounding the price in my head upto those, then let people haggle down again to the number in my head. My sheds so full I'd rather sell a £10 part for a fiver though than have to box it up again, list it individualy on the classifides for a tenner, post it, and still only end up with a fiver.
Will bring a couple of complete bikes too, but they'll be priced more realisticaly.
