Hey edhurl, welcome to GBO! I hope you got an answer to your original question as it seems the discussion has morphed away from it to some degree. But you can tell how emotional the issue of price fixing is by the posts here!
Heck, one poor member was just about tarred and feathered once for posting an item with an exorbitant price on it. He even said so in his post!

But the truth is he just enjoyed the interaction and wanted to haggle a bit.

Me, I don't haggle!
Others may just have an overinflated concept of the value of an item. But that's his right as a seller! An to paraphrase the rules, you don't post something like
"YOU MORON!!!
You want $200 for a barrel I can get from the factory for $160!? Darn idiot...
" Nope, if you don't like the price, don't buy the item or do your haggling with the seller via PM's.
And ya know, I think, as if anyone cares what I think..., that every opinion expressed here is the correct one!

And everyone here may take opposite points of view depending on whether he is buying or selling!
That's fine. No one can say another person is wrong in this area. To use a term I think from Cursillos: Feelings are neither right nor wrong, they're just feelings." What I do if I see an item I want that I think is priced to high, and I don't mean $5 or $10 dollars, I drink that much in beer a night!

Anyway, I PM the seller with an open offer (not a low ball but what I
feel the item is worth to me). The seller is free to accept the offer at any time if he doesn't get the $ he wants.
If I ever sold anything, which I don't, I wouldn't feel right asking for any more then the going rate for the generic item. For example, I wouldn't feel right asking anymore for my 7X57 barrel then I would any other caliber!
Now most will say that's kinda strange, and they wouldn't be wrong. But they shouldn't say I'm wrong because It's just the way I see things.
Stick around pal, you'll find that the folk here are really great people! Most of the time any problem in the classifieds originates with newer members who are used to other, more cut throat, forums!

Everyone should do what you did; ask the question!
Oh, about those questions...

try not to ask ones that give me the opportunity to pontificate!

I do love to hear myself type...
