@curiousjim Thanks.
Anyone who sells below market value is a) not paying attention, b) not very good at 4th grade math, or c) an advocate for the greater good, unselfishly serving humanity.
Or...
(d) wants to get stuff out of their house and that is more important than money
(e) wants liquidity to pay for something else, and timing is more important than profit
(f) probably a bunch of other reasons.
I listed some speakers at about 83% of cost, new. I got very few nibbles. I lowered it to 73% of cost and sold them. I had a clear, detailed description and excellent photos. I was willing to wait 6 months to sell them at the new, lower price. Because, I don't need the money right away and could also listen to them while they were listed.
