“Marks on the underside”

Always include Hi Rez pics of every surface (underside incl) & describe every mark accurately.

Yup singintheblues.  Seems obvious to us.
Hi res photos will do with just a reference to each mark - It's not easy to describe a mark accurately.

Hi rv, first let me mention that I would never return any gear for marks on the bottom, and agree with everyone it was likely a case of buyers remorse.

The only other thing I can think of is that the buyer is a reseller who works on small margins.  And perhaps his selling description would include the marks on the underside and would eliminate his profit.  Just guessing, nothing else.

Again, I would have kept it, but thanks for posting this.

Generally, things sell much quicker on ebay. Although, yes, you can sometimes have to deal with some real turds.....been selling there since 2004 and mostly have had great success. On rare occasions when there is an issue, I make it right to maintain my 100% feedback, which is important. Selling on here? A mixed bag really, limited success. Too many are looking for things other than what I'm selling usually. Oh well...

Everything has been said, but I do agree with geof3. I have never looked at the underside of any piece of equipment that I have bought on Audiogon. Who does that?
