I can think of a few possible reasons. To someone not really thinking about it the dealer's website appears to have more inventory. And by leaving a lot of cues up and marked sold it gives the perception that this guy must have good prices because he sells a lot of cues. It also shows all the cues that pass through the dealers hands so say I'm looking for a SW, the dealer might not have one but I might think "This guy sells a lot of SW's so I'll keep checking back."
Really JV, you don't understand why I as a buyer would prefer it if list prices were kept in the post? There are several reasons, none of which have to do with my willingness to pay for an appraisal. I'm not buying a house for gosh sakes, and even then it is the lender that requires the appraisal. But you are correct, I'm not willing to pay for an appraisal for a cue I do not own (unless it's a jumbo monster). Do you really want all buyers to start having your inventory sent to an appraiser before they buy? Are you willing to send every cue in your inventory from appraiser to appraiser before the purchase? Exactly what percentage of the cues that you sell are sent out to a buyer's appraiser before the purchase is made?
The answer why I'd prefer list prices stay published is really simple - it's good information. Being able to research recent asking prices for a cue is advantageous for the buyer.
If you were looking for a 2003 Camry, would you pay for an appraisal on every car that is for sale, or would you look at the asking prices and go from there?
In most other purchases, the asking prices can be readily researched. Houses, cars, boats, etc. This is good for the buyer. Of course asking price doesn't set the value in stone but do you not get that it is good information for a buyer to have?
Now let me ask a question. If you don't see the value in it for the buyer, why do most dealers post an asking price at all on almost every cue?
Look, I'm not attacking sellers for taking the list prices down, I'm only saying that as a buyer I would prefer the prices to remain posted. Not sure why you tried to make me sound like a nit for not paying for an appraisal on every cue I might consider buying.
