Do people really just not get it that their items are not selling...

I think that quality will always hold its true value and that be said for any product.  It is all comparative.

I sold all six items in one weekend.  I priced them all at what I thought was an attractive price.  Got a few unreasonable low offers but sold four items at asking price.  Now my dentist can make another boat payment.

I urge all sellers to overprice everything and hold it like that. There will be a lot of buyers, just wait for couple of months. That's how you capture the market and inflate the value while creating new normal. Prices are often already inflated. Ten year old piece, whatever it is, with some exception, should cost no more than 10% of its new equivalent. 
When item is priced low and sold very fast, this creates unfair situation when most members can't even see the ad let alone have time to think of whether or not buy it. First come first 'steal', right ? Right. 

The attempt to say ten year old ten percent? Not ever going to be a reality for anything in demand. The actual FAIR MARKET is ’what is a buyer willing to pay". With the realization a seller usually wants as much as possible. In a way inna IS correct in that is enough sellers stay at high prices, it will become the new normal. However, I believe there are enough private sellers wanting to sell quickly, that the high price strategy bet may fail, and all those folks holding too much stock finally give up or go broke.
The only things I bought here were at 30% of retail, and 27% of (the 1987)retail price! I had looked and and wanted an item (a LOT) at 55% retail, and just told myself NO it is 25 years old, just repaired, and I DO NOT NEED IT.

LOOK.

No one has money. Everyone on here is a have-not. Let's just be real. If the item isn't less than $2k it's hard to sell.

Even if you're in the market for a $5-10k item, those are almost all dealers trying to sell new OR they're trying to make a profit from a trade-in or something like that. I have no idea how The Music Room operates but you know damn well they have the system figured out. You can't lowball dealers because they want to make money on the stock.

What's annoying are ads for weird lesser-known brands and which are usually 10+ years old with multiple owners. Look bro, half off of MSRP from 15 years ago for a product without reviews or seen at shows after two owners isn't even remotely a deal. No one is going to buy your CRAP. If you would price ACCORDINGLY you could possibly move it.
