Is this a New Game being played now?

...and seller beware, too.  ;-)

I agree and disagree ! Wherever there is a financial transaction involved you should always "err on the side of caution".
However, even though the situation may look a little suspicious, always remember; - - - you were a first time buyer/seller at some time in the past.
How would you feel to know that people were "blowing you off" because
you had no history with AUDIOGON. 
I think the appropriate thing to do would be to invest a little effort and establish a line of communication; ask for some personal background and do a little investigation of your own, before you draw any conclusions. And of course, make certain it's not an "off shore" scam of some sort.
I have done these things myself years ago, and frankly, it paid off. And, - - - - -  yes, I actually had to blow off a few. Anyone credible should be forthcoming. Frankly, I don't like PAY PAL much but it seems that AUDIOGON is pretty well locked in with them. It can work in your favor, but always be cautious. 

The only thing I ever bought here was 20 years ago, instant membership. All good.
Remember that Agon listings show up on Google and Shark.
Of course you can shut out the majority of the universe if you’re paranoid. And sit on your sale.

I don’t find that a problem. If someone is looking for a certain item they go on HIFI Shark and locate it on Audiogon. They then register on Audiogon and make an offer. The best sales that I have made were from new members. What difference does it make if the buyer pays and you receive payment?
