Why bogus retail price from some sellers?

Yes most resellers give the last highest retail price. So an amp bought at the beginning of production run might be listed with a new retail price of the most recent last sold new amp which could be as much as 15 years younger. The new retail price may have been 50% less at the time. Many dealers sell old stuff at close to new original retail price. I saw one dealer added $1700 to the amplifier list price for used quality NOS tubes - when asked how long the previous owner had used those tubes in a 10 year old amp - a deathly silence and communication stopped - so the tubes could be 10 years old (partially or nearly entirely used up) and the now rare NOS tubes probably cost a small fraction of $1700 10 years ago.

You can’t make this stuff up. It is like the pristine used car I drove an hour to see to find the entire back roof and rear door smashed in from being hit by a garage door (no mention on the listing).

Many stores sell used vinyl “clean” copies for more than original retail price...you can’t make this stuff up.

Frankly I don’t know why sellers do this to themselves. Unrealistic pricing just means no sales for months even years or perhaps these sellers count in the bigger fool principle.

I doubt that sellers artificially inflate their MSRP. Why would they bother? It’s hardly worth the hassle.

They may have been told when they bought them, prices change all the time too as others here mention too. 
 

I don’t see a sea of schemers, I see genuine sellers who have sold their items, without any one calling them out at the time. But life is full of surprises.

 Im with you yogiboy. I messaged a seller that his retail price was incorrect, ( by quite a bit )  He responded by asking what it should be. I told him the correct price using a dealer ad and direct price from manufacturer. He never responded or changed the incorrect price. He has since re-listed the ad 2x, both with wrong retail.. A mistake can happen, but deliberate deception is just wrong.

@winoguy17 I've done the same to 2 different sellers. Still they never changed the price. Still the products went unsold.

I see ridiculous shipping charges too.
