Anyone else receive low offers right away ?

There is also a cultural aspect to trading.
New Englanders tend to want to get their asking price.
As a New Yorker, the asking price is a starting point for negotiation. This is not disrespectful, but cultural.
I once was looking at a house in New England, and the owners would not budge on the price. A month later I got a call from the realtor saying that they had lowered their price. I made another offer, and the realtor said 'why are you doing that, they just lowered their price.'
I replied that they just gave me a new starting point.
We finally reached a deal.
If they had negotiated from their original price, I would have paid more.
Some people just won't pay retail even if that means the asking price on Audiogon.

I'm not insulted by lowball offers, but I do wonder about outrageously low offers within minutes of a posting with a low price (eg, 40% off an item listed at the lowest price ever on the 'Gon). Kind of weird: does the buyer expect the seller to panic within minutes?

It is another matter, when an item has been up a month or two, since there is some indication that the market will not bear the asking price. At this point, I think it perfectly appropriate to offer a "would you consider" reduced price, and I sometimes do this myself.

Perhaps the trigger happy lowballers could exercise a bit of patience; that way, they wouldn't seem so ridiculous, and they might find a deal.

What's the big deal - if you don't like the price just don't sell it and ignore the offer!

Can't justify a buyer offering hundreds less, especially if the seller is asking a reasonable price for his item. If you truly want something, just offer the full price and you have secured it for yourself. On the other side of the coin I have noticed that some sellers are asking a ridiculous amount of money for their gear as if they were trying to retire tomorrow. Right now there is a McCormack DNA-1 with silver upgrade, the seller is asking over two thousand dollars for it. A few years back I was selling those for $900.00 to $1200.00 plus shipping.

This is just an observation on my part and truthfully a seller can ask any price he or she wants, don't mean you will get it. Or possibly as I stated above the selling price was inflated so when low offers come in the seller will get exactly the amount they secretly had in mind.
