Online sellers use OBO to mean "or best offer." If a listing includes this acronym, you can make the seller an offer that's below their asking price. If the seller thinks your offer is fair, and it's the best they receive, they'll likely sell you the item.
On rare occasions, some sellers use OBO to indicate they expect offers higher than their asking price. These sellers may feel insulted when you offer less money than their asking price, but really, it's their fault for using OBO incorrectly.
