100% correct and 95% of the poors here on the ODT will never understand it.
If you have something with real market appeal, gunjoker is your best bet for maximum return unless you're near an auction house that has two "I've got the biggest dick in this town" bidders who constantly go at each other driving prices through the stratosphere.
One good example is a gun of a type that I own has been on GB for a week and has 3 days to go, with a current bid of $1,150. That gun was discontinued less than 6 months ago, and had an MSRP of $700-ish. I anticipate that the auction will hit $1,300.
I'm not greedy, but I'd be dumb not to try and flog mine on GB next week. The gun I'd replace it with doesn't have the mystique of having suppressor-height sights that I don't actually need for my current suppressor
