So you don't pay P&P on here then
Well, of course that depends on whether or not the item is posted. And if it's posted, p&p varies according to how
its posted, and where it's posted to and from. That's why the thread title is "how much is my xyz worth?" and not "how much is my xyz worth including p&p from a to b?"
The 'bold' is the correct answer for all our old stuff
That may be true - or it may not. But in that case the only reasonable response to any price request in this thread would be "put it on eBay and see".
But not everything is sold on eBay, and we know that eBay prices include eBay fees, and aren't always themselves entirely reasonable. That's because collecting old junk isn't an entirely reasonable pursuit, and collectors of old junk aren't always entirely reasonable.
So, to sum up, "how much is my xyz worth?", "how much would my xyz fetch on eBay?" and "how much would it be reasonable to ask for my xyz in the retrobike classifieds?" are three different questions, and may have more than three different answers!
Calmes dans le demi-jour
Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
