No swap meets it similar things somewhat local to you? I'm sure you know that shipping kills selling stuff like you have. Just kills it.
If you price the stuff at its real value, then add in shipping you can never sell the stuff. If you price it so the shipping doesn't kill the deal, are literally giving it away. It's for sure a double edged sword.
Of course, with the country shut down you have even fewer choices. Even swap meets are getting shut down.
You are kinda between a rock and a hard place, unless you can wait out this flu junk and find a swap meet.
