I spoke with a couple of people who tried to help this seller but only received snide replies. Apparently his replies stated "You should find a better way to use your time" or something to that effect.
To me, a good use of time is learning a little bit about what you're selling so you don't look like a fool.
A poor use of time is trying to help a bullheaded, arrogant, obnoxious, know-it-all seller so that's why I did not offer any comments to him.
I've heard this seller has made a number of folks in the club mad. Caveat Emptor.
