What can you do about a nonselling seller?

I agree with Herman: forget about it; life's too short.

For the sake of analysis, my guess is that this seller received an offer before yours. He agreed to sell it, and the buyer paid via paypal, overnight delivery of cashiers check or money order, etc. Until he could confirm payment, he decided to string you along with a delaying tactic. In other words, if the first buyer didn't pay up, he would still have you as an interested buyer. If he had told you the cable was already sold, you might buy one from somebody else (e.g., order it from a dealer) before he could confirm payment from the first buyer. While this is not a nice thing to do, he technically did not lie to you. It appears the first buyer came through with the payment, so the seller was willing to come clean and say the cable was already sold. Find another seller!

If you are a serious buyer, I'd also recommmend you show that you are by giving your complete name, phone #, and delivery information and inquire exactly on how you will be paying for the item. That will get a sellers attention and show that you are serious, instead of, "Yeah, I want to buy that."
I've heard that too many times, on items offered, and most of the time, they don't close the deal when that is all that they initially say.
...and sometime, even when you show that you ARE serious, some sellers will change their mind AFTER making a committment to sell an item to you. I recommend you accurately and honestly post feedback against them when they don't live up to any firm commmitment made.
Good luck and Happy Listening!

I told the seller i would buy it. Ten minutes later i was told the price. Which i knew. I again told him i would buy it. Half an hour later he told it was sold to someone else. Whereas in the first email I expressly stated that i wanted to buy it so the second one, which at that point it was not sold, was a moot point. The seller however has contacted me and has now rectified the situation. So in the end all is well. Thanks

Unfortunitely it goes both ways. Many times when I sell things I get email from persons who say they want to buy it. I follow up with my address and never hear from them again.

So until "the check in the mail" it is still for sale.

Just for the sake of clearity, I am the seller with my son Tigger 0063. The email came saying he wanted to buy and he asked what model, an Elite, Mk I or Mk II. That did not sound like a done deal to me. Now I have made an offer back to him to sell the only other one I own that I am using today in my system. What I get is this discussion?
The advise you have received here Lordgorian is to get on with life, I will email you later to discuss this further.
