Craigslist is still pretty cool but your right there does seem to be an extraordinary amount of dopey people posting stuff for sale lately. They even worse with vintage stuff and antiques. People think just because it’s old it’s rare and valuable and that it doesn’t matter how poor the condition is. I see people post vintage sewing machines for 200 to 400 dollars and some of those would blue book for only 25. Most of those machines aren’t rare either. Unless you have a featherweight that old singer isn’t likely to be rare. Everyone used to have a sewing machine in their home. Singer sold MILLIONS of them. I read that back in the day Singer sold in one year as many machines as all the sewing machine manufacturers put together do in a year now.
I understand how a person might not know exactly how much an item is worth. We posted a 1957 Chevy Bel Air last year. We weren’t totally clueless but we were overpriced. People will let you know pretty quick what your item is worth. I see people posting the same garbage over and over, some of them for years.
