I am a dealer. I am a collector.
As a dealer I buy and sell to make a living. To put food on the table, to pay my rent, to take a vacation, to go to a Mets game.
When someone says to me "I will take it." I put that item aside for them and tell any other potential buyers that the item is sold.
When that initial buyer does not pay in a reasonable amount of time I contact them. When they do not respond I contact them again. This is over the time span of a few days.
By the time I realize that the initial buyer has reneged the second or third buyers could be long gone.
So now I still have the item and no sale.
It has been my experience that when a buyer renegs HE NEVER lets me know about it. NEVER.
Common courtesy is out the door in these instances. All I would expect is an e mail saying, sorry I don't have the money now, I thought I would have it but I do not or sorry I just changed my mind. Just common courtesy and communication.
But renegers NEVER DO THAT. NEVER.
A Net54 member recently did this to me on a $1500 item, which eventually did sell on the bay.
My two cents in this matter.
