FLINT, Mich. -- A simple mistake turned one lucky person into a millionaire.                    

In Flint someone said they mistakenly fed a $20 bill into a lotto ticket machine. They meant to only use $10, but decided to buy a Cash for Life ticket anyway.

It turned out to be a big winner.

It was worth at least $4.1 million. Workers at the store where the ticket was bought say the recent win has business booming.

The lucky person is now deciding between lifetime annual payments of about $200,000 or a lump sum of $4.4 million.

The lottery winner has chosen to remain anonymous.
