Everyone has their own degree of patience for navigating the BS that comes from selling online. Posting on Craigslist usually unleashes a torrent of scam emails in the first 24 hours, but I expect that, so whatever. I buy a lot of stuff on FB that needs to be shipped to me, via 1:1 transactions. You just put in place a process and parameters that you're comfortable with, and if the seller / buyer is on board, great. If not, move on. Always insure packages and require signature, so if the buyer claims it didn't arrive, you get your money back.
