Is Craigslist still the go-to classifieds site in some places?
Around here it’s (very sadly IMO) been almost completely replaced by Facebook Marketplace, to the extent that people make Facebook accounts just to use Marketplace.
I only sell on Facebook marketplace because being able to see someone’s profile means a lot less time spent selling the item.
I use both in the Bay Area and have never succeeded in selling anything on FB. Craigslist usually connects me with some buyer and if not I go to eBay.
I use ND first, then CL. I've used FB a few times, but mostly it's been scammers (though I have friends who swear by it).
