Life is funny. Someone asked a few days ago if it is safe to buy used. I was the first to recommend audiogon...and here I sit 4 days later feeling like I've just been had. I sent a cashier's check through next-day delivery for a Rotel amp I "bought" at audiogon. The FedEx Web site shows package as being delivered and signed for by the seller on the 11th. The seller contacts me today to let me know he has not received anything from FedEx. He has 34 positive feedbacks with no negatives...but something does not feel right. And the bank says there is no way to put a stop payment on the check. Uh-oh. I know this kind of stuff has to happen to somebody...but why me?
