I don't think anyone should have to justify why you are selling & it makes me laugh when I see an ad with various reasons why as if there should be some sort of guilt associated with it.
It's not necessarily guilt...it's called "marketing". Most buyers don't know the sellers, so if the sellers can paint a story that makes the potential buyers more confortable, they can sell quicker (or at a higher price). I'm by no means an "Audiogon Power Seller" or anything of the sort, but when I've needed to, I've unloaded a lot of gear in a very short amount of time at a fair price.
Following this advice, I moved $10k of stuff in under 2 weeks (no joke) - I was unemployed and needed cash for grad school.
1. Pictures are a mustÂ…and not just of the component itself. A photo of the component in a system helps, too. This also shows that the component wasn't used in a pig sty. It gives the buyer confidence that the product exists and hasn't be abused.
2. The product needs a bit of personal narrative. What did you really like about it? What were the products strengths? What similar components have you used?
3. You need to post a reason why you're selling the goods. Make it personal, particularly if the strengths listed above are compelling.
4. List "out the door" pricing. Spell it all out. List the product for $2000, but in the description, say "include a flat $100 for UPS ground shipping and $65 for paypal." And that all goods will be in original boxes, then boxed again.
5. Talk up your reputation. I always say that I take my Audiogon reputation seriously, and anyone who has any concerns should contact those who have left me feedback.
6. Use proper English. Poor grammar stinks of a scam.
7. Make the ad fun. I want to get the impression I'm dealing with a guy I'd want to buy a beer.
8. Make it clear that your posted price is more than fair and not negotiable.
These are the rules I follow, and have been really successful. Bottom line, I post in an ad exactly what I look for in an ad.
