Sellers: When do you drop your price?

" You said this was your first sale on Audiogon.  I didn’t check but I assume you don’t have any feedback ratings."

The OP did not say it was his first sale on AG, he said it was his first sale. He does have AG feedback and the ad is on AudioMart.

I tried to sell a pair of speakers here a month ago. They were brand new, they didn’t work well with my amp but they were high end and decent speakers. Regardless what I listed it for, all the offers came in at around 55% of the original price. First I felt insulted. I didn’t understand why everyone’s offer was so low. Later I found out they wanted to flip it for a profit. Given that it was brand new, box, warranty and all, I still think it was disgraceful. I later figured that eventually someone will pay slightly more, someone who won’t flip it. It’s a matter of time. I would check how many of the same items are up for sale and if you want to sell, price it at the lowest or slightly lower than - and offer something extra

Just for your information so that you know all used  equipment is 50% off that's a given.

If there are any glowing reviews of your item, include a link. USAudiomart
is free. Not so here. Shark picks up pretty much everything so most
buyers look there first.
Maybe your question really is: "How do you price an item"?

" Just for your information so that you know all used equipment is 50% off that's a given"
that is true 20% of the time 100% of the time
