It's up to you to specify the terms of your sale.
"Price is firm.' (no offers considered) for example.
"Lowballers will be politely ignored." etc.
What to do with very low offer on an item for sale
I am pretty new to selling on Audiogon and with a component I have received an offer of 25% of the price; I had chosen a price, including shipping, at the low end of what I have seen on HiFi shark.
If someone with more experience than I could help; do I ignore it or come back with a sensible (10% perhaps) discount on my price.
Thanks for advice
