Quoted from 30FathomDave:
I've always found "FIRM" to be a bad business move. People like feeling like they got a deal, especially when spending thousands of dollars.
If you truly are firm on your price, price it just a little bit higher than that, and let your would-be buyer haggle you down to your firm price.
You get what you wanted, and the buyer feels good about themselves for negotiating a better price. Win-win.
The only time it makes sense IMO is when you've already lowered the price a few times, and you've truly reached the point where you're just looking to get your "rock bottom" price.
I don't understand this. If priced reasonably, you either want it or you don't. Cut the crapola and either buy it or don't.
Expecting a few hundred off is fine on an OBO pricing, but when it's priced reasonably and labeled as firm I find it "bad business" by the buyer to insist on that same few hundred dollars off on the firm price. Sure, it never hurts to ask, but some sellers prefer to skip the haggling nonsense when it's time to sell an item. Most collectors know what price will sell a game and what price will not.
