My list of seller red flags

agree, items listed as New, then the description says only used 20 hours...

OK, OK, I adjusted my "Gimmicky Pricing" from $1899 to $1875.

Will it fly off the shelf now?

I agree with many of the 'naysayers' here
Overpriced is a subjective perception, unless you keep up with recent selling prices for the unit. Even then, a component that has been taken care of meticulously by a true audiophile may deserve to ask for more than recent sales prices

Not everyone likes to haggle. It's not part of our American culture for Pete's sake! IMO, asking for an amount you KNOW you are not going to get just so you can haggle with interested would-be buyers is worse than stating your price is firm! If the price is firm and fair, heck yes I'll buy it.

" agree, items listed as New, then the description says only used 20 hours..."

Well, think of it this way. You just bought a new car and drive over to friend's house 4 days and 80 miles later to show him. Do you say: " How do you like my new car or How do you like my used car?"

Great.  Another buyer that wants everything on a silver platter.  NIB, with receipt, 1080P or 4K quality pictures and a description that reads like an audio review.   For a price that is 50% of FMV....for a used item.   Guess what, we ALL want that, but understand that it is not realistic.  

Don't like how the ad is constructed, move on.
Don't like the quality of pictures included in the ad, move on.
Don't like the price, move on.
Don't like how the seller responds to questions, move on.

Early in the thread, someone mentioned selling a McIntosh piece without an original McIntosh box.   I do understand this concern, but it can be addressed.   I have shipped numerous McIntosh items- MR71 tuner with case, 2100 amp, c28 without case, c28 with case.....all without a MAC box.  But I carefully packed, and made sure to add extra protection for the face.   I built a shipping crate for the MR71.   My cost was about $25 in materials, and about 30min of my time.    All pieces arrived intact.

I buy and sell all the time- I like to swap equipment.   I never sell because I have to.  I set my price(s) based upon current and repeatable FMV- I seldom use the highest price in my comparisons.   

I respond to low ballers with a price that is HIGHER than my original asking price.   They get the message quickly.  Reasonable offers are politely countered.

When I submit an offer that a seller considers "low" or "low ball" I always try to have records of recent sales in front of me to prove why my offer is fair.   This strategy has worked more often than not- sellers who want to sell understand they are not selling in vacuum and if their price is too high they will be married to the item.

People try to overthink the process, and end up as bitter neurotic shut ins.   Don't like something- move on !
