FB Marketplace / Craigslist are usually quite effective. I would list it a little above what you want for it and then give in to a little haggling. e.g.
I ignore lowballs, but if the offer is reasonable I usually counter with something like, "I did want to get a bit more for it, but I would be ok with splitting the difference if you can meet at [place convenient to me vs. somewhere far away from me convenient for the buyer]"
The main thing I've learned from selling in these marketplaces are: 1) Never re-arrange your plans for a buyer. It doesn't happen often, but I've had people flake last minute which is always annoying. 2) Try and do the deal close to where I live. Some folks will want you to drive miles only to haggle you more when you get there. Remember, they are getting a deal, so they should come to you.
Deals should always be win:win. If you're not happy, then don't do the deal. Someone else will come along if you've priced it fairly.
