Anyway what happened was a woman payed the $8.5 for it on auction day, then a few months later, someone who missed out at the auction offered her $12, which she obviously accepted.
So why did the 2nd buyer who was obviously willing to go a LOT higher than what it sold at auction for, stand by and stop bidding? Why would he let the woman get it for $8.5M when he was presumably willing to go as high at $12M? Unless you mean 'missed the auction' as opposed to 'missed out at the auction'?
