I find that somebody that is a collector is usually more than happy to pay the going rate as they wish to own an item .
Dealers on the other hand knock you down considerably .
I know you don't have to accept their offer , but most of us only sell when we have something else in mind .
Some people seem to take advantage of this .
Others buy and sell for pure profit.
Despite usually being happy with what I've received for goods , it's annoyingly to see the item then advertised on freeads or wherever for considerably more .
