Do you have a low seller rating? Perhaps people are scared off. I imagine if you listed the PSP pre-Christmas, it would have gone for silly money. Or pounds sterling and lots of it.
I haven't sold anything on ebay yet - got not much to sell. A few old computer games and stuff might fetch a few fivers, and some pathetic Warhammer/Citadel minatures from my youth. I have however recently started my hat collection on ebay and now own 1 hat! A straw trilby so I can look like a nobhead in public without having to have it tattooed onto my face.
I've just sold a signed Manchester United painting to a box holder at Old Trafford. It was given to me by my dad. He won it at an auction in 2001 for £3000. The company paid for it. I've just sold it for £1400. It's only worth about £800, so it's not too bad I s'pose.
Collie, nice to see you've joined in with the hat collection. However, you have a long way to go before you can beat my mighty 5 beanies & 3 Yankies. In Hatland, I must be a God to you.
Those blasted pirates of Penzance! There's probably one right now with your small straw hat on his head, and one too for his parrot on his shoulder. But fret not, he'll surely hang when he returns to port.
