It's not your fault Gene, this part of the site is for discussing records and this was an interesting one to discuss, a very interesting one.
I sympathise with the buyer, but also the seller in a strange way, I know what it's like to sell a very expensive record for next to nothing then someone else comes along and offers loads more than what I just sold it for - in fact it happend on here last week, that Clicky whatsit 45 I was selling, I took an offer then immediately got offered £200 on top of that - by two separate people - despite me announcing that it was sold.
I'd already agreed a sale so it went for the original price to the original buyer - however, if it had been MY record and not someone else's - and my financial situation was as bad as it usually is - then who knows, I might have had to say look, I can't turn down this extra £200 quid I've just been offered.
I've also been usurped on records I'd been promised, by some very well known names. It just gets written in the black book and I don't deal with them again. At the end of the day, money talks.
