I've not used it before, but while looking for a bike* recently I noticed that my old lumicycle bits were worth some money to people.
Personally, I've only sold stuff that is worthless to me and cluttering up the shed, so I sell for a fair but cheap price, rather do that than have the hassle of bargaining or of not managing selling it, and it's good to know that the stuff will end up being used .- recycling innit.
Only slight confusion I have is about how and whether to let people 'bag' things subject to pictures or whatever. Any opinions on that?

*I bought new in the end – seems like the percentages people will take off a 2nd hand bike don't really make it cheaper than buying a new one in the sales.
