Unfortunately, it's hard to post prices upfront anymore because people have just become really inconsiderate these days. As a cue seller, you spend countless hours going through websites, Ebay, dealer's lists, etc. to find deals where you can make a profit. A seller has overhead and expenses just like any other business and these must be covered as well as hopefully, a little profit margin at the end. You have to gamble and take risks that sometimes turn out bad. Occasionally, you find a diamond, but this seems to be the exception nowadays.
After you spend hours finding the deals, and usually some that aren't so great, you come up with something for sale. You decide what you need for the cue and then you post it for sale. What happens? Immediately, there are nits, twits, and self proclaimed defenders of the weak, telling you and anybody else that looks at your ad what it cost, what they think a proper pricing level is, where you got it from, and all the history that they or anyone else thinks it might have had. Now, if they were truly buyers, they could simply negotiate to acceptable terms, or go on to the next deal. These people aren't a bit interested in buying, though, they just want to feel important or like a crusading hero to the weak who can't make rational decisions on their own, I guess.
These folks never seem to notice the cue you bought and sold at a loss to cover weekly bills, or that you bought "in great condition" that you end up selling for half because it was a piece of junk that you sure wouldn't pass on like it was presented to you. They find the Palmer window cue that you found in a pawn shop for $100 (after hitting the pawnshops for years) that you marked up to a real market value to offset your losses. You didn't screw anyone, but you sure get made to feel like you're running a shell game.
Don't get me wrong, it's one thing to warn fellow AZB'rs about a fraud or misrepresentation, but a legitimate business deal should be between a buyer and seller, not the peanut gallery. That's why I choose to PM people prices.
By the way, I do hate when a person asks me to make an offer. I don't have any clue what they need for it and I don't want to be insulting. Sellers do this, obviously, to maximize their profits and not leave money on the table, but I think that pricing should, at least, have a baseline that can always be negotiated.
