Facebook already lets you post for-sale ads in a group if it set up for it, it even reminds you from time to time to take down your ad if you have sold it. They do not take any commission for it and rely on you to you use your common sense as if you were selling in a newspaper.

Or nextdoor. Which reminds me, I want to get more of my neighbors to join that.

YMMV with Nextdoor . THe only thing I can vouch for about my neighbors on Nextdoor is that they're all batshit insane racists.

Sounds like me might be neighbors.

Seriously boggles the mind what people are willing to say on Nextdoor.

Nextdoor already has classified ads. It's basically just like Craigslist, but with a smaller more local audience.

FB? You mean, the place that puts counterfeiters as both ads and "Suggested Posts" in my feed daily?
