Given that it was a lot auction though, and as you said, instant cash in a lump sum, a starting offer of $700 would have been ideal, and a final offer of $750 would have been
fair. If he would have chopped it all up individually on ebay, he could have scored a tad over 800 bucks or more easy. On the lot auction, he would have already been taking a small loss on market value, as whoever bought it would be doing it for resell reasons with no intention of paying for the total worth, plus the final value fee he would have to pay on that and the paypal fee would have ate a chunk. So while what you deem as a decent offer for him at $650, which I have to admit is lowball, for him it would be worse because ebay and paypal would take their nice large chunk of the sell also making it totally unrealistic to want to accept that offer. Regardless, as stated prior, and why I dont like people jumping on this forum and just doing sales, they find stuff dirt cheap, go to ebay hoping to make a ton, they fail, they come here, make up stories and spin about their prized collection they are so attached to (that they got like last month), etc, then list the stuff here for ebay, or even above ebay prices.
I don't expect them to not make any profit on their lucky finds and great deals, but I at least expect them to act intelligent in regards to prices, treat people with courtesy, stop making up background stories about shit, and not feel entitled, because no one has the
right to buy or sell here, its a privilege. And in regards to this community, I personally think that privilege should be earned, not just handed out on a whim to anyone right from the get go. If people were actually forced to slow down and participate in the forums, over time the odds are they would learn what the actual going rates of said items are, instead of the quick guesses they made after viewing a couple current BIN auction listings.
