It was probably a good idea a few years ago, but I think every man (or woman) and his dog is doing it these days. I can remember reading stories in the papers about someone buying a little ornament at a car boot sale for 20 pence, putting it on eBay and getting something like 17 quid for it. It might still be worthwhile but just remember, tinks, you may have to register yourself as a business seller (as oppose to private) in which case you'd be eligible for taxes... eBay, together with the taxman, are taking all the fun out of selling on there.
