body: I would like to sell items online, and came across [this story about a person who sold a $40 printer](http://www.indystar.com/story/news/2016/06/06/he-sold-40-printer-then-he-sued-indiana-30000/85219140/) and ended up (so far) paying over $12,000 in legal fees.
  
  
  What could I do to prevent this situation on a site like Craigslist?
