I have been selling items on about 7 different local facebook groups in my area for about a year now. Works well for some items not so well for others. I have a new rule for myself, I have to get at least $20 or more for an item I attempt to sell on there, as it is not worth my time otherwise. My biggest issue where I live is most of the people in theses groups are low income or just want to get things for nothing, or they are very flaky, some items sell quickly, others take a while. If I can easily ship the item, I sell it on eBay, because even after shipping and fees I can usually get at least double what I can selling it locally. I do not have a CL local to where I live or I would do Craigslist intead, less drama. The groups in my area have too much drama, they have even set up 2 other groups to complain about people in the selling groups. And evrytime somone gets mad or banned they try to start their own selling group, it is a circus.
