CAN SOMEONE EXPLAIN TO ME THIS?

The person may still be making money at 50% off. For example:
I bought four Canton 300CD speakers($1,000. each retail) new (NOT DEMO), from a dealer, for $350. each. Also three 360CD ($750. retail, for $200 retail, each) I didn't 'need' them, just at the price, I decided I could use them for a 5.1 system... maybe.
They are still worth, used, way more than I paid new. Deals like that come along. Folks buy stuff for cheap they do not want or need, with the 'possibility' that they will want it 'down the line'.
I found a Sony SCD333ES for $200 new.. I use it. Some have sold them for way more.. and I bet they paid what I paid.
I DO use my Cantons... those other people may decide to sell the items.

I think both cases are pretty common. Sometimes we just get to buying stuff on impulse and after it arrives check it for damage but never really integrate into the system and decide to resell when we get around to it. I did that with a fairly expensive MSB DAC. I never even checked it out and resold it with no problem. Also I sometimes think it's a way to sell a new item out of territory and but still make money on it.

Bingo! I once bought a pair of $1800 (retail) speakers from a dealer across the country. He had them listed as demos. When they showed up, the boxes had never been opened. I paid about $1200 for them, a good deal for me and of course he still made money.

Creative selling.

Saw this one a few months ago: New, only used for a few hours.

Emailed the seller and his reply was that because they were used less than 5 hours they were still considered new. I've heard of the 5 second rule; do we have a 5 hours rule in audio?

LOL.

Many times dealers will sell product through AudiogoN. Some will even sell brand new product, but they cannot advertise it as such. So they try to imply that the product has been as lightly used as possible, just for advertising sake, they cannot list it as 'NEW'.
