Seriously interested buyers.. yeah right!

Why is it that when I put stuff for sale on newsgroups and online classified ads, there's always a bunch of people claiming that they are "seriously interested", and then end up being not interested after all? WTF is wrong with you people? Ask questions, that's fine, but don't say you are interested if you don't know yet! And there are those who offer you trades... my add does not say "for trade" or "for sale or trade", does it? It baffles me... I even got someone offering me puppies in exchange for a 51" TV I sold not long ago... o.O

I'm currently selling an iMac. I know it's a big purchase for a potential buyer, we're selling it for $1200. So I understand that people would have doubts about making that purchase. I know it's a good deal, I know it works flawlessly, but it is understandable that people would have doubts. I mean if the machine is so good, why do I sell it, right? (I previously wrote a blog about why, so I won't go into detail again, but simply put, it was just not cutting it for the use my wife was making of it - and you cannot upgrade an iMac unfortunately). So that's why asking questions and even coming to see it and try it out is a good idea. The last person being "seriously interested" was supposed to come last Saturday, and the way he talked, he was coming to pick it up. Then he called saying he was sorry but he could not come because he did not know that his bank was closed on Saturdays, and at the ATM, he has a daily limit. So he would come Sunday instead, with a second daily limit withdrawal. Understandable, and he seemed honest. I told him it was no trouble. Comes Sunday... he did not come by. He didn't even call to say he wasn't coming. Seriously interested? Yeah, maybe he was too embarrassed to call again to cancel or something, but then he did not think that maybe he was preventing us to do other things... which he did not, but that's beside the point.

Anyway, that was my rant for the day I guess. The iMac is still sitting on a desk, waiting for some new-owner love....
