Facebook Is A Cesspool

I joined FB because I was looking for a truck. Craigslist seems dead. I found a truck, and thought I would sell off some stuff I don't need on FB market place. Nothing has sold. I had a guy contact me about an A body radio for$25.
I get a message "I want the radio, where can I meet you?" I tell him, then he says it's for his friend, and can he have my number. I give it to him. Guy calls, and wants to give me $20. I said no. He gets mad, and hangs up. Another guy(I guess) contacts me through regular text. Says he wants the radio. I ask how he got my info. Nothing.
The first guy messages me again today, and wants to meet me tonight, after 5. I told him I won't meet people at night. I will meet him this weekend. No reply.
One of my biggest peeves, is it seems most FB people want very close to new prices. Sometimes more than new. Why would I buy it from FB people, when I can get it from Summit, and not have to pay shipping, and if there's a problem, I can send it back. Oh well....
