I usually ascribe to the adage, "If it's too good to be true, it probably is," but, sometimes, I've looked at stuff that seemed too good to be true -- but it WAS true! I have purchased items up to $1000 less than the going rate USED.
Certainly, you must know your seller. A phone call usually helps develop confidence.
On the other hand, I've also had questions about buyers. Recently, I was about to accept a credit card payment from a buyer in Indonesia when I saw a reference to credit cards on another audiogoner's sale listing as not being acceptable. When I contacted him, he told me there are scams with credit cards from Indonesia. I asked the "buyer" to wire the money -- and never heard from him again.
