[Seinfeld Moment]
If someone has an item for sale for "$100 or best offer," and you are the first to offer the $100, should you get the item despite possible future offers? Does "$100 or best offer" mean $100 or best offer less than $100, or best offer regardless of the $100? If the latter, why mention the $100 in the first place, and when does the offering period end? Did Seinfeld ever do a bit on this?
