I have been buying and selling on ebay for a few months now. It is one of those things I often looked at but never got round to doing.
If you don't use ebay, start now. I have bought all sorts of useful bits and bobs, but the best bit is selling. I have made about 300 quid since Christmas selling old vinyl, bits and bobs from my folk's loft, old mobile phones people were throwing out, and general junk people have been throwing out.
I even sold a pair of worn DM boots for £16.00.
There are freaks out there who buy worn DM's, there are even freaks you may have seen on Graham Norton who buy worn football socks. Here is a freaky example:

The pink pound is where the moneys at. Those who used to work in Blackstar will remember the huge amounts of money that guy made referring customers through his collection of gay interest sites.
