I noted on an Aussie selling site they advise do not pay until a firearm is delivered into the hands of the transfering dealer. A requirement in Australia is a firearm must be transferred via a dealer or another authorised licensee eg club, police officer, depending on the state.

That's a new recommendation.

I'm guessing frauds have occurred.

The legal requirement to transfer through a dealer probably doesn't exist in much or any of the USA.

I always wondered how people trusted strangers so much to just send them lots of $$$ for a sight unseen item bought online. The correctly or not described product, condition aside, some might never send any product at all.
