Buyers can be very fickle and unpredictable. Guys will trip over themselves ordering the new (and overpriced) VisionLine GG-1 at $1190, yet I've had just one lone response thus far showing "casual interest" for an unblemished, Like-New, Lionel JLC GG-1 for $450. 
Really???
Newsflash people... It ain't going any lower than that. 
If it doesn't move at that price, it's staying on my roster. 
Selling trains here on the forum from time to time, I've seen my share of surprises relative to what moves quickly and what lingers for weeks -- or sometimes months. I was very surprised that the Lionel 18" Santa Fe High-level Superliners took a few months to move. They were as MINT as the day I bought them. And you just don't see that kind of stuff hit the market very often, if ever. Yet because I wasn't "giving them away", they sat for awhile until the right buyer came along.
Everybody, myself included, likes a great deal. But sometimes I think sellers on the forum have "conditioned" buyers to behave a certain way. 
I prefer to post things at VERY fair prices. And on occasion, I'll offer ONE price reduction as a "show special" as an extra incentive (if it sits for awhile). But as a general rule I don't offer daily price reductions of $10-$25, because that only conditions buyers to expect yet another price reduction tomorrow. And it more than likely sends a message that the seller needs cash quickly -- which may or may not be the case at all.
More importantly, I don't think a $10-$20 price reduction is gonna make that much of a difference on a $500+ item, because if somebody were truly interested they could OFFER the seller that difference without "needing their permission". I get offers for less-than-the-asking price all the time. Sometimes I'll go for it if the offer keeps the deal in win-win territory. Other times, I'll reject the offer if it falls into the win-lose category -- something I've needed to do on occasion, because I'm not in the market of giving stuff away.
Yet there are days I honestly think buyers here are just WAITING for sellers to give stuff away. And I guess that simply indicates to a large degree how much of a toy train glut exists out there on the market today. 
I agree with Mario's earlier post, when he said folks' eyes just glaze over after a certain point.
