I would like to share some of my recent findings made while selling a pair of big high dollar ARC 610T amps. First, I can tell you there are a lot of BS folks out there placing low-ball bids from accounts with no feedback. I even ended up having to block several from bidding because they wouldn't stop when contacted. When you do penetrate a layer further (analyzing their email message header, etc.) on some of these folks you will find they are not who or where they claim to be. The anonymity the Internet, and that which Audiogon provides, unfortunately lends itself to this type of misuse. So, just be aware and try to know who you are dealing with. Additionally, I was horrified as I researched the many ways a seller can be scammed. PayPal is absolutely not on your side as a seller! If the buyer claims he never received a shipment, you may get charged back the full amount, even if you have moved the money out of PayPal and can show shipping paperwork. Cashiers checks are also apparently a big risk these days too. If the check is drawn on a bank besides the one where you are cashing it, the bank won't be able to tell if it's good until it goes to the clearing house, which may take a day or a week. Moreover, once the check clears the bank may still hold a portion of the money additional time per their internal rules, maybe weeks. If you receive a bad check and cash it, the bank will come back to you for the money once the check hits the clearing house and is returned and it could be up to you to prove you didn't do it on purpose. The safest way I have found to do business, is to establish a rapport with the buyer and know who you are dealing with as much as possible. Then, especially if the deal is high dollar, have the buyer obtain and over night a cashiers check from a national bank where you can go cash the check at a branch on your end immediately. I have accomplished this from start to finish in less than 24 hours.
