That's why you meet someone at a police stationThey take about 2% that's hardly gonna break the deal is it? On top of that they provide seller's protection as well as buyer's protection so you won't lose your money and you can claim the cost of it back if it gets lost in the mail.
Whereas Craigslist and GumTree don't provide that and you are open to scamming or outright being taken advantage of physically if you are dealing with a nutcase with bad intentions.
eBay is your best bet if you want a quick sale.
