Or they send a fake PayPal notice that overpays then claim it was an accident & that the difference was to go to the shipping co or courier and u have to send those funds by Wells Fargo or some other untraceable means.
Happened to us by listing a large used printer.
The immediacy and inability to bother asking for a better price was the first clue... And as soon as the fake pp payment notice was sent an almost mechanical "oops we overpaid" email was rec'd.
Like what u said - mechanical response.
